Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described by means of implementation examples with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Fig. 1 is a flowchart of a calibration method according to an embodiment of the invention. The technical solution of the present embodiment is particularly suitable for the case of shortening the time of each preset correction process by extending the correction period of some preset correction protocols. The method can be implemented by the correction device provided by the embodiment of the invention, and the device can be implemented in a software and/or hardware mode and is configured to be applied in a processor. The method specifically comprises the following steps:
s101, determining the use frequency of each preset correction protocol in a preset correction list of the medical ray equipment.
The preset correction protocol in this embodiment corresponds to only one correction protocol, and the preset correction list is a set of all preset correction protocols. The present embodiment describes taking a medical radiation device as a radiation imaging device as an example, taking a preset correction protocol as an air correction protocol (air correction protocol).
The radiation imaging device may be a device for performing medical imaging through radiation, such as CT, digital radiography (Digital Radiography, DR), and breast machine (mammagraph), or a radiation imaging modality device of a multi-modality medical device, such as PET/CT, RT/CT, or a device for performing medical treatment through radiation, such as radiation therapy device (Radiation Therapy). Taking CT as an example, the empty correction protocols required by different scanning positions are different, and the scanning positions corresponding to different CT apparatuses are generally different, for example, the main scanning position of the CT apparatus in the department of cerebral surgery is the brain, the other scanning positions are fewer, the main scanning position of the CT apparatus in the department of thoracic surgery is the chest, and the other scanning positions are fewer. The frequency of use of the respective air correction protocols in the air correction lists of the different CT apparatuses is different. In order to make an accurate air correction plan, the present embodiment periodically counts the use frequencies of the respective air correction protocols in the air correction list of the target CT apparatus to determine the air correction plan according to the use frequencies of the respective air correction protocols.
The method for determining the use frequency of each air correction protocol comprises the following steps: firstly, determining the times of each scanning part scanned by the ray imaging equipment in a preset statistical period; and then determining the use frequency of each empty correction protocol in the empty correction list according to the scanned times of each scanning part and the empty correction protocol corresponding to each scanning part.
S102, dividing all preset correction protocols into a necessary-scanning protocol group and an optional protocol group according to the use frequency of each preset correction protocol, wherein the use frequency of the preset correction protocol in the necessary-scanning protocol group is larger than that of the preset correction protocol in the optional protocol group.
It will be appreciated that the main scanning area of the CT apparatus is a basic requirement thereof, and that the non-main scanning area is an additional requirement thereof. In order to ensure the imaging quality of the CT apparatus, the present embodiment must ensure the stability of the basic requirement thereof, and also ensure the stability of the additional requirement thereof as much as possible. I.e. by executing the null-check protocol of the necessary sweep of the null-check protocol suite, the basic requirements of the user are guaranteed, and by executing the null-check protocol of the optional protocol suite, the additional requirements of the user are guaranteed.
And S103, when the preset correction signal is detected, controlling the medical ray equipment to execute all preset correction protocols in the necessary scanning protocol group and part of preset correction protocols in the optional protocol group so as to complete the current preset correction task, and enabling each preset correction protocol in the preset correction list to be executed at least once when the preset correction tasks of preset times are finished.
It will be appreciated that when the user initiates an air correction task, it is typically necessary to input an air correction signal to the radiographic imaging device, and therefore when the processor of the radiographic imaging device detects the air correction signal, an air correction process is initiated, controlling the radiographic imaging device to perform each of the air correction protocols in the scanning protocol set and to perform a portion of the air correction protocols in the optional protocol set to complete the current air correction task, and causing each of the air correction protocols in the air correction list to be performed at least once at the end of a preset number of air correction tasks. In other words, each time the air correction process is performed, each empty correction protocol in the protocol group is necessarily scanned, and part of the protocols in the optional protocol group are simultaneously performed, and after the preset number of air correction processes, all the empty correction protocols in the optional protocol group are performed at least once. Only part of the air correction protocols in the optional protocol group are executed in each air correction process, so that the correction period of the air correction protocols in the optional air correction protocol group is prolonged, the number of the air correction protocols executed each time is reduced, and the time of each air correction process is further shortened.
Wherein, each empty-correction protocol in the protocol group is ordered according to the frequency of use, and the ray imaging device executes each empty-correction protocol according to the ordering of the empty-correction protocols.
The empty correction protocols in the optional protocol group can be ordered according to the use frequency, so that the radiographic imaging equipment executes a certain number of empty correction protocols each time according to the ordering; a certain number of empty correction protocols can be randomly selected from the remaining empty correction protocols in the optional protocol group to be executed in each air correction process. Preferably, the embodiment may further call the current reserved scanning record, determine all scanning locations corresponding to the reserved scanning record, and use the empty correction protocol in the optional protocol group corresponding to all scanning locations as the optional protocol to be executed on the same day. Optionally, if the empty-calibration protocol corresponding to the reserved scanning record is not executed within a preset time period, the empty-calibration protocol is put into the necessary-scan protocol group. For example, when a brain of a patient needs to be scanned on the same day, but a preset correction protocol corresponding to the brain is not executed within one month, the preset correction protocol can be put into a necessary scanning protocol group, so that the accuracy of brain scanning on the same day is ensured.
Optionally, the empty correction protocol in the optional protocol group is divided into a preset number of optional protocol combinations, and the preset number is equal to a preset number of times. Determining the executed sequence of each optional protocol combination; when the air correction signal is detected, the ray imaging device is controlled to execute each air correction protocol in the necessary scanning protocol group, each air correction protocol in the corresponding air correction protocol combination is executed according to the executed sequence to complete the current air correction task, and each air correction protocol in the air correction list is executed at least once when the air correction task of the preset times is finished.
Optionally, the optional protocol group includes at least a first group and a second group, and the frequency of use of the null-correction protocol in the first group is higher than the frequency of use of the null-correction protocol in the second group. When the air correction signal is detected, the ray imaging device is controlled to execute each air correction protocol in the necessary scanning protocol group and partial air correction protocols in the first group and partial air correction protocols in the second group so as to complete the current air correction task, so that each air correction protocol in the air correction list is executed at least once when the air correction task of the preset times is finished.
The second group comprises the empty correction protocol set of the optional protocol group, and the rest part of the empty correction protocol set corresponding to the scanning part contained in the scanning record in the preset statistical time is subtracted from the empty correction protocol set. The preset correction protocol of the group is a rarely used null correction protocol, that is, a null correction protocol which is rarely used by the radiographic imaging device at ordinary times, but in order to enable the radiographic imaging device to cope with any imaging situation, the embodiment also lists the radiographic imaging device as a null correction protocol which must be executed, and only the correction period is long.
Alternatively, the number of empty correction protocols performed by each air correction process is the same, so that the time taken for each air correction is substantially the same.
The technical scheme of the correction method provided by the embodiment of the invention comprises the steps of determining the use frequency of each preset correction protocol in a preset correction list of the radiographic imaging equipment; dividing all preset correction protocols into at least a necessary-scanning protocol group and an optional protocol group according to the use frequency of each preset correction protocol, wherein the use frequency of the preset correction protocol in the necessary-scanning protocol group is greater than that of the preset correction protocol in the optional protocol group; when the preset correction signals are detected, the medical ray equipment is controlled to execute all preset correction protocols in the necessary scanning protocol group and part of preset correction protocols in the optional protocol group so as to complete the current preset correction task, and each preset correction protocol in the preset correction list is executed at least once when the preset correction tasks of preset times are finished. The basic requirements of the user are ensured by executing each preset correction protocol in the protocol group to be scanned every time of preset correction, and the time of each preset correction process is shortened by properly prolonging the correction period of each preset correction protocol in the selectable protocol group on the basis of ensuring the basic requirements of the user.

According to the technical scheme of the correction device provided by the embodiment of the invention, the use frequency of each preset correction protocol in the preset correction list of the radiographic imaging equipment is determined by the determination module; dividing all preset correction protocols into a necessary-scanning protocol group and an optional protocol group according to the use frequency of each preset correction protocol by a grouping module, wherein the use frequency of the preset correction protocol in the necessary-scanning protocol group is larger than that of the preset correction protocol in the optional protocol group; when the execution module detects the preset correction signals, the medical ray equipment is controlled to execute all preset correction protocols in the necessary scanning protocol group and part of preset correction protocols in the optional protocol group so as to complete the current preset correction task, and each preset correction protocol in the preset correction list is executed at least once when the preset correction tasks of preset times are finished. Each preset correction is executed to scan each preset correction protocol in the protocol group to ensure the basic requirement of the user, and part of the preset correction protocols in the optional protocol group are executed to properly prolong the correction period of the preset correction protocols in the optional protocol group, so that the time of each preset correction process is shortened by properly prolonging the correction period of each preset correction protocol in the optional protocol group on the basis of ensuring the basic requirement of the user.

The preset correction protocol in this embodiment corresponds to only one correction protocol, and the preset correction list is a set of all preset correction protocols. In this embodiment, a preset correction protocol is an air correction protocol (air correction protocol) as an example, and a medical radiation apparatus is described as an example of a radiation imaging apparatus.
The radiation imaging device may be a device for performing medical imaging through radiation, such as CT, digital radiography (Digital Radiography, DR), and breast machine (mammagraph), or a radiation imaging modality device of a multi-modality medical device, such as PET/CT, RT/CT, or a device for performing medical treatment through radiation, such as radiation therapy device (Radiation Therapy). Taking CT as an example, the empty correction protocols required by different scanning positions are different, and the scanning positions corresponding to different CT apparatuses are generally different, for example, the main scanning position of the CT apparatus in the department of cerebral surgery is the brain, the other scanning positions are fewer, the main scanning position of the CT apparatus in the department of thoracic surgery is the chest, and the other scanning positions are fewer. The frequency of use of the respective air correction protocols in the air correction lists of the different CT apparatuses is different. In order to make an accurate air correction plan, the present embodiment periodically counts the use frequencies of the respective air correction protocols in the air correction list of the target CT apparatus to determine the air correction plan according to the use frequencies of the respective air correction protocols.
The method for determining the use frequency of each air correction protocol comprises the following steps: firstly, determining the times of each scanning part scanned by the ray imaging equipment in a preset statistical period; and then determining the use frequency of each empty correction protocol in the empty correction list according to the scanned times of each scanning part and the empty correction protocol corresponding to each scanning part.
It will be appreciated that the main scanning area of the CT apparatus is a basic requirement thereof, and that the non-main scanning area is an additional requirement thereof. In order to ensure the imaging quality of the CT apparatus, the present embodiment must ensure the stability of the basic requirement thereof, and also ensure the stability of the additional requirement thereof as much as possible.

It will be appreciated that when the user initiates an air correction task, it is typically necessary to input an air correction signal to the radiographic imaging device, and therefore when the processor of the radiographic imaging device detects the air correction signal, an air correction process is initiated, controlling the radiographic imaging device to perform each of the air correction protocols in the scanning protocol set and to perform a portion of the air correction protocols in the optional protocol set to complete the current air correction task, and causing each of the air correction protocols in the air correction list to be performed at least once at the end of a preset number of air correction tasks. In other words, each time the air correction process is performed, each empty correction protocol in the protocol group is necessarily scanned, and part of the protocols in the optional protocol group are simultaneously performed, and after the preset number of air correction processes, all the empty correction protocols in the optional protocol group are performed at least once.

Preferably, the embodiment may further call the current reserved scanning record, determine all scanning locations corresponding to the reserved scanning record, and use the empty correction protocol in the optional protocol group corresponding to all scanning locations as the optional protocol to be executed on the same day. Optionally, the protocol group which is not executed in the preset time in the empty correction protocol corresponding to the reserved scanning is put into the necessary scanning protocol group. For example, when a brain of a patient needs to be scanned on the same day and a preset correction protocol corresponding to the brain is not executed within one month, the preset correction protocol can be put into a necessary scanning protocol group, so that the accuracy of brain scanning on the same day is ensured.
