It is a figure which shows each process of a heavy particle beam therapy information management system. It is a figure which shows the relationship between each process of heavy particle radiotherapy and heavy particle radiotherapy data management. It is a system configuration figure of a heavy particle beam therapy information management system. It is a figure which shows the display form of a client terminal. It is a figure which shows the display image for irradiation record creation management. It is a figure which shows the relationship in each process of a fixing tool preparation report. It is a figure which shows the detailed screen of a fixture preparation report.

  First, as an embodiment of the present invention, an overall system of a heavy ion beam therapy information management system 11 is shown in FIG. The heavy particle beam therapy information management system 11 includes a heavy particle beam therapy process management system 12, a heavy particle beam therapy data management system 13, and a heavy particle beam therapy data analysis system 14.

  The heavy ion beam treatment process management system 12 includes an irradiation record creation management system 15, an information sharing management system 16, and a schedule management system 17. The irradiation record creation management system 15 manages a series of work flows and creates an irradiation record as will be described later. The information sharing management system 16 supports HIS, interface with irradiation equipment, and human-type information sharing. The schedule management system 17 has a planning function for how many patients can be treated in advance, a reservation schedule function from preparation to completion of treatment when a patient to be treated every day occurs, and a real-time schedule function for changing the schedule of the day. And manage from the annual schedule to the daily schedule.

  The particle beam therapy data management system 13 includes a database system 18 and a search system 19. The database system 18 accumulates information derived from a patient centered on irradiation records and information derived from devices such as irradiation devices (device standard settings, calibration data, setting data, etc.) in a database and stores them in a searchable state. The search system 19 is used to search data stored in the database system 18 for data that hospital staff such as doctors need in their respective positions.

  The heavy particle radiotherapy data analysis system 14 has a function of summing up and analyzing treatment information of various patients and information derived from irradiation equipment in cooperation with the heavy ion radiotherapy data management system 13. For example, doctors evaluate the survival rate using the Kaplan-Meier method in association with a protocol (a template that determines the number of irradiations depending on the organ with cancer and the stage of progression) and a treatment plan. Improving quality. In addition, referring to the patient's past condition and treatment effect, etc., it is utilized as decision support information for determining the protocol and treatment plan for the next treatment. For engineers and medical physicists, when trouble occurs, obtaining information from the irradiation equipment and patient contributes to the investigation of the cause of the trouble, and for nurses, it helps patients such as the patient's psychological condition and physical condition. By obtaining close data, it is possible to realize delicate nursing.

  Next, the work flow of heavy ion radiotherapy will be described with reference to FIGS. First, an order is issued from the HIS to the heavy ion beam therapy information management system 11. Subsequently, the patient receives a consultation at the hospital reception (S11). In this reception, the examination and photographing necessary for the examination are instructed, and the patient goes to the examination room and / or the photographing room and undergoes examination and / or photographing. The patient who has undergone the examination and / or imaging goes to the examination room and sees a doctor (S12). When the patient receives a doctor's diagnosis that the heavy ion beam treatment is necessary, the treatment is accepted (S13). At this time, information such as introduction of another hospital or introduction of another department is also recorded as irradiation record information. When the treatment is accepted, the patient enters the treatment planning room, is examined again, and adaptation is determined (S14). In this examination / application determination, irradiation record information such as CT images, lesions, presence / absence of metastasis, and infectious diseases is created.

  After the examination / application decision is made, the patient's treatment policy is determined (S15). In this treatment policy determination, irradiation record information such as a protocol, combined use with other treatments, a schema diagram, preprocessing information, and a patient schedule is created. When the treatment policy is determined, a fixture for fixing the patient based on the determined treatment policy is created in the fixture creation room (S16).

  Next, CT simulation is performed in the SIM room (S17). In this CT simulation, a patient is fixed to the created fixture and CT imaging is performed. Based on this CT photograph, a doctor inputs a portion to be treated on a computer, and a dose distribution is created. By this CT simulation, irradiation record information such as a CT image list is created. Thereafter, a treatment plan is performed in the treatment plan room based on the obtained irradiation record information (S18). By this treatment plan, irradiation record information necessary for irradiation such as port information and patient positioning information is created. Treatment discussion is performed in the conference room based on the created treatment plan (S19). By this treatment discussion, irradiation record information such as a dose distribution map and patient positioning information is determined with reference to information created by the heavy ion beam treatment process management system 12.

  When the treatment plan is determined by the treatment discussion, an order for a compensation filter (a dose adjustment device adapted to the shape of the patient's cancer) is placed (S20). Irradiation record information such as compensation filter data and production schedule is created in this compensation filter order.

  Next, the QA / experiment mode is performed in the treatment room (S21). In the implementation of the QA / experiment mode, irradiation record information such as a dose, an atmospheric pressure, and a measurement result is created. After the QA / experimental mode is implemented, treatment rehearsal is performed in the SIM room for necessary patients (S22).

  After the rehearsal, the treatment irradiation with the actual heavy particle beam is performed in the treatment room (S23). In the treatment irradiation, the irradiation is performed based on information such as the positioning of the irradiation and the dose determined in the treatment discussion. With the end of treatment (S24), an execution record such as the number of irradiations and dose distribution for each port is created and transmitted to the heavy ion beam treatment information management system 11 to create irradiation record information. CT simulation (S17), treatment plan (S18) has cancer site and dose distribution data as planned values, examination and approval are made at treatment discussion (S19), and actual values at treatment irradiation (S23) Is obtained. Thereafter, follow-up is performed (S25). This follow-up will follow up the treatment.

  In the present embodiment, the irradiation record information created in each process from reception (S11) to follow-up (S25) in the heavy ion beam treatment information management system 11 is digitized, stored as searchable data, and tabulated and analyzed. Realized and enables centralized management of treatment information and support of treatment by treatment information.

  FIG. 4 is a system configuration diagram of the heavy ion beam therapy information management system 11. The server 31 shown in FIG. 4 is mainly provided in a hospital. The server 31 includes a graphic user interface module (GUI) 311, an interface module (I / F) 312, a schedule module 313, a search module 314, an irradiation recording module 315, a data management module 316, an analysis module 317, a communication module 318, a database 319 and an operating system (OS) module 320 are provided.

  The schedule module 313 is related to the schedule management system 17 and is used to schedule a treatment appointment for a patient. For example, the treatment module 313 can perform the treatment appointment in a method described in Japanese Patent Application No. 2009-212190. The irradiation recording module 315 is used for receiving information from the client terminal 33 and creating irradiation recording information. The data management module 316 is related to the heavy ion radiotherapy data management system 13, and records and searches information in cooperation with the search module 314 and the database 319. The analysis module 317 analyzes data and information stored in the database 319. The communication module 318 is used for communication between the server 31 and the client terminal 33, the server 31 and the HIS, and the server 31 and an irradiation device such as an accelerator via the interface module (I / F) 312.

  The server 31 is connected to the network 32. The network 32 is connected to a plurality of client terminals 33 provided in hospital staff and treatment resources (treatment planning room, fixture creation room, SIM room, conference room, treatment room, etc.). When irradiation record information is input from these client terminals 33, the irradiation record information is sent to the server 31 via the network 32 and stored in the database 319.

  In the client terminal 33, it is necessary to simultaneously browse information and input data in each process for each patient of heavy ion beam therapy, and if there is one screen, there is a case where the amount of information cannot be displayed sufficiently. Therefore, a plurality of screens are prepared in the client terminal 33. In the present embodiment, as shown in FIG. 5, two displays (two screens of an input screen and a patient information screen) are provided for one client terminal. For example, one display is used for inputting information and the other display is used for information reference. A plurality of tags are arranged on the screen, and when the tag is selected, a corresponding screen is displayed. Since a plurality of screens (irradiation record information) can be displayed at the same time, it is possible to input necessary information from the input screen while opening several screens and viewing them. Input by the hospital staff, these pieces of information become irradiation records for each patient, sent to the server 31 via the network, and stored.

  Next, a display example of each process of the irradiation record creation management system 15 will be described. When the patient ID is input with reference to the patient information input screen displayed on the display of the client terminal 33 in the treatment reception (S13) of FIG. 2 and FIG. 3, the patient information is displayed on the display. The treatment schedule is displayed. In accordance with this schedule, the reception instructs the patient to perform examinations and radiographs for particle beam therapy. For example, in the CT room, when an engineer inputs a patient ID by referring to the input screen of the display of the client terminal 33 of the engineer, the site to be imaged by the patient is indicated on the display, and the engineer displays the indicated site on the CT. Take a picture. The captured image is sent from the client terminal 33 to the server 31 via the network 32 and stored in the database 319.

  In the examination / adaptation determination (S14), when the doctor inputs the patient ID according to the screen of the display of the client terminal 33, the input screen and the patient information screen are displayed on the two displays, respectively. On the patient information screen, a tag for selecting an image necessary for diagnosis / adaptation judgment is displayed. When the doctor selects the tag, for example, a CT image of the patient is sent from the server 31 via the network and displayed on the patient information screen. The doctor sees the patient information screen and enters information such as the location and size of the cancer, whether this cancer is within the range that can be treated with heavy ion beams, or whether it has metastasized, referring to the patient information screen. To do. The information input in this way is stored in the server 31 via the network.

  In the treatment policy determination (S15), as shown in FIG. 6, the treatment order is received at the client terminal 33 in the treatment planning room. At this time, a list of patients to be treated is displayed in the patient list area of the display of the client terminal 33. When the doctor selects one patient from the patient list, a treatment order request confirmation screen (* 1) for that patient is displayed. Specifically, when a patient is selected, the patient list area is closed, the patient information area is shifted to the left, and the business base area is displayed on the right side. In the patient information area, information on the treatment patient corresponding to the work, for example, treatment policy, information on treatment irradiation, and an information input screen are displayed. In the business base area, input assistance and editing for the patient information area can be performed.

  When the request content is confirmed on the screen * 1, the doctor selects a corresponding tag in order to acquire information necessary for determining the treatment policy. By selecting tags, treatment plan summary screen * 2 for viewing treatment plan summary, pre-treatment work instruction screen * 3 for pre-treatment work instructions, instruction diagram creation screen * 4 for creating instruction diagrams Schedule creation screen * 5, treatment start confirmation screen for confirming treatment start * 6, explanation and consent for explanation and consent screen * 7 fetches the corresponding information from the server 31, and the display of the client terminal 33 The doctor receives the support of the information displayed on each screen, makes a decision according to each screen, and inputs information necessary for treatment with reference to the input screen. These pieces of input information are sent to and stored in the server 31 via the network.

  In the treatment discussion, provisional selection of protocols, provisional assignment of schedules, and input of fixture creation instructions are performed via the client terminal 33. Information generated by these operations is sent from the client terminal 33 to the server 31 via the network 32 and recorded in the database 319.

  When the treatment policy is determined as described above, preparation of the fixing device is started. In this case, the fixture creation engineer operates the client terminal 33 to select the fixture creation report screen * 8 based on the tag. In this fixture creation, schedule creation on the day, patient presence information (reception), change on the day, entry into the fixture creation room, patient identification / confirmation, fixture molding, patient plan confirmation, creation work / finishing, fixture creation report input ID label creation, fixture registration input, fixture storage, and implementation summary are performed. In the creation of the current day schedule, the current day schedule is referenced, printed, and the schedule is entered in consideration of patient information up to the current day. In the patient presence information reception, it is determined that it has been received by an ID card (or terminal operation). In patient identification / confirmation, the patient is collated using the confirmation screen of the ID card and the terminal.

  In the fixing tool mold taking, the captured image of the part and the instruction content are displayed, and the work content is captured by the digital camera. In patient schedule confirmation, the next schedule is confirmed at the reception, and the next schedule is printed and distributed. In the fixture creation report input, report information of the created fixture is input and displayed on the fixture report screen.

  In ID label creation, a barcode to be attached to the fixture is created, and the created barcode is attached to the fixture. In the fixture registration input, the barcode ID is registered in the server 31. Check if the bar code fixture is recognized. In the fixture storage, the storage location number is registered in the server 31. In the implementation summary, the server 31 notifies the HIS that the fixture has been created.

  In the creation of the above-described fixing device, specifically, several templates are prepared for how many times the irradiation is performed in the treatment policy determination, and the templates are assigned. The fixture is determined according to the assigned template.

  When the fixture is created, in the SIM room, the doctor or engineer selects the tag displayed on the display of the client terminal, and captures CT simulation report information for CT simulation from the server via the network. The captured CT simulation report information is displayed as a CT simulation report screen * 9 on the display of the client terminal. In this CT simulation, the CT simulation is performed on the patient according to the information displayed on the CT simulation report screen * 9. In this CT simulation, a doctor identifies a treatment site, and determines the direction in which the particle beam is irradiated to the site and the irradiation center (isocenter) of the site.

  In CT simulation (S17), for example, schedule creation transfer on the day, progress display, patient presence information (acceptance), change on the day, patient entry, patient identification / confirmation, patient entry / fixture delivery, posture imaging conditions, treatment table movement -Laser point verification, treatment plan CT imaging, fusion image transfer, simple treatment plan, DR image imaging, patient schedule confirmation, CT simulation recording, and notification of execution are sequentially executed. In the progress status display, the patient of the CT simulation is viewed on the patient list screen. In the body posture imaging conditions, the body posture, slice thickness, respiratory synchronization, and the like are input to the CT. The treatment plan CT imaging has two purposes of calculating a dose based on this image and temporarily determining an isocenter on the CT image. In fusion image transfer, PET and MRI data in PACS and CT data in heavy particle PACS are synthesized. In the simple treatment plan, the body position, isocenter position, and snout position are determined. In DR image capturing, the treatment simulator positioning system is operated and positioning is performed. In the patient schedule confirmation, the next schedule is confirmed at the reception, and the next schedule is printed and distributed. In the CT simulation recording, a report for an instruction, implementation data import, and digital camera image registration are performed. At the timing of receiving the implementation summary, the HIS is notified that the CT simulation has been performed. Information generated in the above CT simulation is sent from the client terminal 33 to the server 31 via the network 32 and recorded.

  When the CT simulation (S17) ends, a treatment plan (S18) is performed. In this case, the treatment plan report screen * 10 is displayed by selecting the tag of the treatment plan report screen * 10 for the treatment plan from the display screen of the client terminal 33. In this treatment plan, a treatment plan is created when information regarding the treatment plan is input to the client terminal 33 by the hospital staff with reference to the treatment plan report screen * 10. That is, fusion image transfer, doctor contour input, calculation request input, calculation, calculation result confirmation, work record, calculation end notification, calculation result confirmation, treatment plan storage, and rehearsal instruction input are performed. In doctor contour input, a doctor inputs a contour at a client terminal and generates information to be input to the server side. In the calculation request input, the irradiation direction, dose, number of times, irradiation method, and the like are input. In the calculation result confirmation, confirmation is performed by the server 31. In the work record, work record, analysis data, DVH and the like are input to the server 31 from the client terminal 33. In the calculation result confirmation, the server 31 is used for confirmation. In the rehearsal instruction input, presence / absence of rehearsal is input to the server 31. Also, an implementation summary is notified to the HIS.

  When the treatment plan (S18) ends, a treatment discussion (S19) is performed. The doctor selects the tag indicating the treatment discussion screen * 11 for treatment discussion from the display of the display of the client terminal, whereby the treatment discussion screen * 11 is displayed. In this treatment discussion (S19), the hospital staff discusses treatment by looking at the patient image displayed on the treatment discussion screen * 11, and the plan approval, schedule confirmation, and change patient schedule confirmation are performed. In the plan approval, the approval status is registered in the server. In schedule confirmation, treatment plan data is fixed, the schedule is switched from provisional to decision, compensation filter data is created, and treatment parameters are transferred to the treatment apparatus. The patient schedule confirmation at the time of change adjusts the next schedule that the patient will visit when the treatment date changes.

  When the treatment discussion (S19) ends, compensation filter ordering (S20) is performed. By ordering this compensation filter, the dose in the two-dimensional shape and depth direction is adjusted according to the shape of the cancer when irradiating, and a test shot is performed once. Based on this trial hit, data creation, data registration, data delivery, work / inspection, ID label sticking, compensation filter reception, delivery acceptance inspection, registration, and storage are performed.

  When the compensation filter order (S20) is completed, the QA / experiment mode (S21) is performed. In QA / experiment mode, treatment room maintenance, QA phantom loading, QA phantom installation, accelerator QA mode / accelerator energy setting, water temperature measurement or room temperature measurement, barometric pressure measurement, dosimeter operation / setting, dosimeter information confirmation, worker leaving room Beam irradiation, measurement result reference, measurement result confirmation, trend confirmation, pass / fail judgment input, and cleanup are performed. These operations are taken from the server 31 and performed with the support of information displayed on the display.

  When the QA / experiment mode (S21) ends, rehearsal (S22) is performed. The doctor clicks the tag indicating the rehearsal report screen * 12 for rehearsal from the display screen of the client terminal, whereby the rehearsal report screen * 12 is displayed. The patient is rehearsed for the patient by referring to the information shown on the rehearsal report screen * 12.

Is done. In this treatment irradiation, with the support of information displayed on the irradiation record execution status confirmation screen * 13, particle beam therapy, that is, particle beam therapy is performed on a patient by a doctor, an engineer, a physicist, and a nurse. Specifically, when the doctor determines the lesion and the number of times of irradiation, the doctor refers to the input screen of the display and inputs the lesion and the number of times of irradiation to the client terminal. Thereby, the client terminal calculates a single dose. The calculated dose and number of times are displayed on the display of the engineer's client terminal, and the engineer performs particle beam irradiation according to the display information.

  In this treatment irradiation (S23), schedule creation / transfer on the day, display of progress, confirmation of patient presence, confirmation of change on the day, confirmation of treatment / fixture preparation, pre-treatment, changing clothes, treatment hall entry, treatment room decision, Patient entry, patient identification / confirmation, irradiation parameter transfer, irradiation device setting confirmation, patient fixation, treatment table movement, laser point verification, X-ray two-way DR imaging, positioning irradiation, patient exit preparation, patient exit, etc. are displayed on the display This is performed based on the support of information displayed on the irradiation record execution status confirmation screen. In the preprocessing, the processing content is recorded. In preparation for patient exit, changes in the patient's psychological factors are recorded.

  After treatment, cleanup, patient schedule confirmation, treatment irradiation record transfer, summary of implementation, treatment / fixing device cleanup, medication, and accounting are performed. In patient schedule confirmation, the next schedule is confirmed at the reception, and the next schedule is printed and distributed. In the treatment irradiation record transfer, information on the irradiation apparatus is transferred to the server 31 via the network 32 and is held there.

  At the end of treatment (S24), the doctor changes the treatment period or changes the schedule at the end of the treatment. The final decision on the schedule is made. In addition, for each protocol, support for the next inspection, etc., and check whether it is performed within the period.

  In the follow-up (S25), patient presence information confirmation, patient identification / confirmation, treatment record reference, medical examination, patient schedule confirmation, and statistical processing are performed. In the patient presence information confirmation, it is determined that the ID card (or terminal) has received the information. In patient identification / confirmation, the patient is collated using the confirmation screen of the ID card and the terminal. In the treatment record reference, the progress record of important data and follow-up information are referred to. In examination and patient schedule confirmation, statistical processing is performed using accumulated data of the server in statistical processing. Specifically, follow-up is a follow-up observation. For example, if irradiation is performed 4 times a week and 16 times of irradiation is performed, the doctor observes side effects and the presence or absence of recurrence after the 16 times of irradiation. . Such a test is performed after the treatment, but not only the particle beam but also the state of the patient after the treatment is observed in cooperation with other departments such as an endoscope department. The observation result is input to the client terminal as irradiation record information and stored in the database of the server via the network. For example, data relating to the course of treatment of a patient treated with several doses at any dose is statistically collected. The necessary data is searched from the collected data, and the searched data is aggregated into a graph.
