Abstract

PURPOSE:To effectively utilize an LAN by sending a picture necessary for a medical examination to a picture terminal with classifying it into three reserving mode, an automatic mode and an immediate mode. CONSTITUTION:The reserving mode, which transmits picture data to picture output terminals 3A to 3M in a consultation room according to the medical examination department receiving information of a hospital information system, the automatic mode, which automatically transmits the result of the photographed picture to the picture output terminals 3A to 3M in the consultation room when the photographing of the picture in the departments (picture input terminals 1A to 1N) executing inspections is completed, and the immediate mode, which directly transmits the picture data necessary in the process of the medical examination from picture data bases 2A to 2L to the picture output terminals 3A to 3M on or almost on a real time basis, are prepared. The picture is classified into the three modes, and the picture necessary for the medical examination is transmitted. Thus, since the modes except for the picture transmission in the immediate mode have a leeway in a transferring period, the picture can be transferred by selecting the inactive time of a local area network 100 by control of the host computer 10.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a medical image system, and in particular to an interoperable system with a hospital information system to efficiently transfer images such as X-ray data and computed tomography data during medical examinations. This invention relates to a medical image system that has been combined.

[Conventional technology]

Traditionally, in this type of medical imaging system that files a large amount of digital images, the most commonly handled image data from medical examinations is film taken as the result of X-ray examinations. .

Traditionally, these films were stored in packages in the order in which they were taken or for each patient, but this required space and was not easy to search. were stored on optical discs.

That is, X-ray film is collected from an image input terminal with a film digitizer, and
(hereinafter referred to as CR) and computed tomography (hereinafter referred to as CT) are collected from image input terminals that have these interfaces. This image data is typically stored in an image database. but,
There is a series of cases in which a patient undergoes imaging and then undergoes a medical examination based on the data, and moreover, diagnosis is often made by comparing with previous image data. This method will be explained from the aspect of image transfer with reference to FIG.

A medical image system according to the conventional technology includes image input terminals 80A to 8ON that output images obtained by medical examinations as images converted into digital image signals, image databases 60A to 60L that store these images in databases, and necessary images. It consists of image output terminals 70A to 70M that make requests for images and display received images, and a local area network (hereinafter referred to as LAN) 101 that connects these terminals.

Therefore, images from X-ray examinations carried out in radiology departments and the like are captured on film, so they are passed to the image reader 82 to become digital signals, and the contents are transmitted from the image terminal 81 to the L.
Image database 60A-60 through AN 101
The data is transferred to the L processor 61 and stored in the database 62 under its control.

When a doctor in a medical department refers to these images during a medical examination, the images of the patient's X-ray examination are first read out from the database 62 through the LAN 10I and displayed on the image terminal 71 at the image output terminals 70A to 70M in the examination room. Regarding the above, attempts have been made to display and refer to the necessary number of images (including not only recent examination images but also previous examination images in order to see trends) and perform medical examinations.

[Problem to be solved by the invention]

The problem with the conventional technology that the present invention aims to solve is that the LAN becomes congested because the search and transfer of necessary images are required at the same time before or during the consultation. It is necessary to limit the number of terminals that can be accessed, as it takes a long time to respond (responses in case of a request).

An object of the present invention is to provide a medical imaging system that solves the above-mentioned drawbacks.

[Means to solve the problem]

The medical image system of the present invention includes: a plurality of image input terminals into which captured images converted into digital electrical signals obtained in medical examinations are input; a plurality of image databases in which the images are stored in databases; and necessary images. A plurality of image output terminals for requesting images and displaying received images, and a plurality of terminals disposed as input/output display means for a host computer, patient information, and image information are connected by a local area network, a reservation mode in which images stored in the image database are read out according to reservation information input from a storage terminal and stored in a file of the host computer and transferred to the image output terminal; and a reservation mode in which the images are collected from the image input terminal. and an automatic mode in which the image is transferred to the image output terminal;
and an immediate mode in which images stored in the image database are retrieved in accordance with a request from the image output terminal and transferred to the image output terminal.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and FIG. 2 is a flowchart showing the usage status of the embodiment of the present invention.

First, an overview of this embodiment will be explained.

In order to efficiently transmit image data, as soon as it becomes clear that image data needs to be transmitted prior to a medical examination,
It was decided that the images would be transmitted in advance from the image database to the memory (for example, a magnetic disk device) of an image output terminal provided in the examination room. The transmission mode is a reservation mode in which image data is transmitted to the image output terminal in the examination room according to the department reception information of the hospital information system (HIs), and a reservation mode in which the image data is transmitted to the image output terminal in the examination room in accordance with the reception information of the department in the hospital information system (HIs). The automatic mode automatically transmits image data to the image output terminal in the examination room, and the instant mode transmits image data required during the examination directly from the image database to the image output terminal in the examination room in real time or close to this time. .

Next, the configuration and operation of this embodiment will be explained.

This embodiment includes an image input terminal IA-IN, image databases 2A to 2L, image output terminals 3A to 3M, and a terminal 5.
The host computer 10 is connected to a LAN 100.

First, image input terminals IA to IN and image database 2A
~2L will be explained. These are created according to the amount of input data for each examination target, for example, by considering the combination of the number of CR/CT or magnetic resonance examination (hereinafter referred to as MHI) (for example, image databases 2A to 2L according to the number of examinations per day). (may be divided or shared) and are usually distributed.

The image input terminals IA to IN each consist of an imaging equipment interface section 11, an image terminal 12, and an image reader 13, and the image reader 13 digitizes the X-ray film image.
It is displayed on the image terminal 12. The imaging interface unit 11 connects with imaging equipment such as OR-CT-MRI that inputs digital images. The image databases 2A to 2L each include a processor 21 and a database 22, and are used to store imaging conditions and image data for examining patients.

The image output terminals 3A to 3M each consist of an image terminal 31 and an image management section 32, and are mainly arranged in examination rooms and interpretation rooms, and are designed to display image data and interpretation reports that are patient examination results. There is. Image management section 32
As a result, a directory of image information is displayed on the image terminal 31 to identify which doctor requested the image to be taken, which patient, when the examination was performed, and which part of the image.

Further, the host computer 10 includes a processor 10A, a memory IOB, a console type terminal 10C, and an interface IOD, and controls the hospital information system (Hl, S) and the medical image system (PAC8). Terminals 5A to 5L are terminals external to the host computer 10, and are placed in reception, accounting, each medical department, radiology department, etc., and input, output, or display information such as reservations, medical reception, and medical orders for patients. .

Here, the usage situation of this embodiment will be explained with reference to FIG. 2.

First, a patient who requires a test such as CR-CT-MRI performs a reception procedure at a hospital (step 41).

The patient then registers at the appropriate or desired clinical department and receives a medical examination. As a result, the doctor
If a test such as RI is deemed necessary, the test item and date and time are entered on the terminal 5C and a reservation is made. Note the reservation results! The data is stored in JIOE (step 42). The patient completes the reception procedure on the day the test is scheduled (step 43).
). Subsequently, the patient accepted at the medical department receives a designated medical room and at the same time goes to an examination department such as a radiology department and undergoes an examination (step 43). Past image data of this patient stored in the database 22 is sent to the image terminal 31 in the designated examination room and stored therein (step 45).
). This is the content of reservation mode.

Next, the image of the examination that the patient underwent in the radiology department or the like is digitized by the imaging equipment interface unit 11 or the image reader 13, and sent via the image database to the image terminal 31 in the examination room of the patient designated in advance from the terminal 5C. 0 or more are automatically transferred to (step 46) the contents of automatic mode.

In addition, in the case of treatment only on the same day, the image and interpretation report transferred in the reservation mode are displayed on the image display terminal and the treatment is performed.

In this manner, the doctor performs a medical examination while referring to past images and their interpretation reports, as well as images obtained in the day's examination and their interpretation reports (step 47).

Also, when other examination images are needed during this examination (step 48), the necessary images are requested from the terminal 31 in the examination room, obtained in real time or close to this, and used as examination materials (step 48). 49).

This series of operations is the immediate mode.

When the medical examination is finished, the payment is completed using the slip at the accounting counter located at the terminal 5B (step 5).
0).

As described above, in the present invention, images necessary for diagnosis are not sent all at once, but are sent classified into three modes.
Since there is plenty of time for transfer, except for image transmission in the immediate mode, a time when the local area network 100 is quiet (for example, when the number of transactions per unit time is less than a predetermined number) is selected under the control of the host computer 10. It becomes possible to transfer.

Furthermore, the image output terminal is used as a display terminal in the examination room and as an image interpretation terminal in the interpretation room, and even if the same model is used for both, it is necessary to use the appropriate model for each. For example, it is also possible to use a high resolution type for the image reading terminal and a normal resolution type for the display terminal.

〔Effect of the invention〕

As explained above, the present invention classifies images necessary for medical examination into three modes: drive mode, automatic mode, and immediate mode, and sends the images to the required image terminal in real time. With the exception of the immediate mode, which requires near-second transfer, it is possible to send data when the LAN is not busy, which has the effect of making effective use of the LAN possible.
