Next, the individual functions of the above components will be described with reference to the flowcharts of FIGS.

Modality 11 The patient ID of the patient to be examined before the examination technician starts the examination,
The examination ID and the requested department name are input to the modality after seeing the request form. The modality adds an inspection date and a modality name, and is used as supplementary information for each inspection. When inspection images 1 to n are collected,
The modality issues an image ID for each image. When the examination is completed, the examination technician inputs an examination end command. When the inspection end command is input, additional information of the inspection and
All images collected by the inspection and their image IDs
Is transferred to the database 13. If the request form is digitized, necessary information is selected from the examination list by inputting the examination ID. (FIG. 5).

When the inspection is completed by the digitizer 12 offline modality, a film and an inspection request form are present. Therefore, first, an empty partition card is taken out of the partition cards stored in numerical order on a partition card shelf installed near the digitizer. Next, the partition card number of the partition card is read by the bar code reader on the digitizer. Then, looking at the examination request form, the patient ID, the examination ID, the site, the modality name, and the request department are input. At this time, the ID is read by a barcode reader, and other information is input by a keyboard. When the input is completed, an inspection request form is put on the shelf containing the partition card.

Next, a partition card is attached to the head of the film, and the film is set on the digitizer together with the partition card. The digitizer reads the set card and the film at the same speed as the automatic processor one by one without disturbing the order. That is, the barcode of the partition card is read first, and then the image of the film is read sequentially. Therefore, the read image data is made to correspond to the partition card number information. At this time, the digitizer issues an image ID for each image data so that each image data can be specified. When all of the inserted films are digitized, the capture-side auto-feeder is activated, and the next inspection film is loaded into the digitizer. When the last film is digitized and sent out, the automatic feeder on the take-out side is operated. When the reading of a series of image data is completed, the image data and the already input information are corresponded by using the partition card number. At this time, the digitizer issues an inspection date, adds the inspection date to the associated image data, and creates data for one inspection. The data for one test is transmitted to the database 13.

The inspection film that has been digitized as described above is stored in the shelf of the corresponding partition card number.

It should be noted that the film can be created by an online modality, but in this case, the film need not be digitized. Therefore, when an image is input to the film, the digitizer or the database ignores the image. (FIG. 6) Workstation 14 As described above, the workstation 14 performs the functions of image reading preparation, routine image reading, and request department reference. These functions will be sequentially described.

Preparation for image interpretation An inspection request form is brought to the workstation. The reading preparation button on the workstation is pressed. At this time,
The workstation is ready for interpretation. Next, the examination ID (barcode) attached to the examination request form is read by a barcode reader, and the examination ID is sent to the database 13 to request a patient ID. Database 1
When the patient ID is received from 3, the patient ID and the examination ID are displayed side by side. When the coincidence between the patient ID and the examination ID is confirmed, the coincident patient ID and the examination ID are stored in the correspondence table, and the collation of the ID for the next examination request is performed in the same manner as described above. In this way, the processing is performed for all the examination request documents, and the matched patient ID and examination ID are sequentially stored in the correspondence table. If the patient ID and the examination ID do not match, the examination ID in the examination request is read again, and the same processing is repeated.

When the collation of the ID is confirmed, the preparation for image interpretation is started from the patient whose confirmation has been completed as follows. That is, the patient ID is extracted from the correspondence table between the patient ID and the examination ID. The patient ID requests the patient's exam list, report, and image from the database. When the examination list, the report, and the image are sent from the database 13, the information is stored in memories (magnetic disks) 41, 42,
44. Thereafter, the patient ID of the next patient is read from the correspondence table, the same processing is performed, and the examination list, report, and image of the next patient are stored on the magnetic disk. When information about all patients is stored on the magnetic disk, preparation for image reading is completed.

In the preparation for image reading, among the patient data stored on the magnetic disk, all the patient data whose latest examination date is three days ago are erased, and the patient ID and the examination ID are erased from the correspondence table. You. (FIG. 7).

Routine interpretation (FIG. 8) The inspection ID attached to the inspection request form is input by being read by a bar code reader. The patient ID is searched from the correspondence table by the input examination ID. Examination list, examination ID, examination date, modality, region, interpretation result, patient ID corresponding to retrieved patient ID
Is read from the magnetic disk and displayed. The latest inspection and the previous inspection are automatically selected from the displayed information. The selected image ID and image data of the latest and previous inspections are extracted from the magnetic disk, and the extracted image data is subjected to data decompression processing and displayed. At this time, the inspection date is also displayed. The image ID of the displayed image, the examination ID, and the number of the display on which the information is displayed are stored. Next, the report of the previous inspection is read from the magnetic disk and displayed.

The image displayed by the above steps is subjected to some processing such as moving, deleting, enlarging, gradation processing, C
When performing processing such as AD and overlay entry / display, the processing is performed as follows.

A display for displaying an image to be processed is designated. At this time, the designated display displays all of the examination ID and the patient ID of the image displayed on this display. Inspection ID required from displayed ID
Or, search for the patient ID and specify it. This allows
An image corresponding to the designated ID is read from the magnetic disk and displayed. Next, the content of the above-described processing to be performed on the displayed image is designated. As a result, the specified image is processed with the specified content.

If the processing content is an overlay entry,
The filled-in overlay is displayed and the overlay data is stored.

For this overlay entry, a touch panel having a plurality of pressure-sensitive pixels arranged in a matrix is used. The touch panel is connected to, for example, a CPU, and the difference in the touch area between when the touch panel is touched with a touch pen and when the finger is touched, that is, the difference in the number of pressure-sensitive elements, the CPU determines whether the touch panel is touched with a touch pen or with a finger. Distinguish whether or not it was touched. When the input is made with the touch pen, the CPU determines that the input information by the touch pen is overlay information, and determines that the input information input by the finger is command information.
Based on this determination, the overlay information is displayed over the image, and the command information is used to perform a predetermined process on the image.

After the processing specified by the command is performed, the display position of the image is determined, and the image is displayed at the determined position on the display. At this time, the image I
The correspondence table including D, the examination ID, and the display number is updated. At this time, it is determined whether to register the processed image. When registering, the registration button is pressed.
As a result, a new image ID is issued. Next, a processing image registration request is made to the database. The database registers the processed image according to a predetermined registration method in response to the registration request. If no registration is made, no operation is performed.

The physician observes, ie, interprets, the image displayed or processed as described above, and inputs the findings to the dictaphone using a microphone. Thus, the interpretation is completed.

Report input This function is used to input the test ID and report, and then
This function is to send an examination ID and a report to a database by specifying an end input, and to print the examination ID and the report.

When executing the report input, the user inputs the test ID and the report while listening to the voice report in association with the test ID of the request form. The input information is read and stored in a memory built in the control circuit 52. At this time, since the input information is displayed on the display, if the displayed information is incorrect, it is corrected and stored in the memory again. If the display information is correct, termination is instructed. At this time, the examination ID and the report are sent to the database in association with each other. At the same time, the examination ID and report are printed on the request.

Refer to Request Department This function is substantially the same as the routine reading function. That is, if the patient ID is a barcode reader, keyboard or O
It is input using a CR or the like. This input patient ID is retrieved from the correspondence table. If there is a patient ID in the correspondence table, information on the patient with this patient ID, that is, the examination ID, examination date, modality, site, interpretation result, and patient ID are extracted from the correspondence table and displayed. Select the latest test and the previous test from the displayed information. Image ID of selected latest and previous inspection
Then, image data is extracted from the magnetic disk, and the extracted compressed image data is subjected to data decompression processing and displayed. At this time, the inspection date is also displayed. The image ID of the displayed image,
The examination ID and the number of the display displaying the information are stored. Next, the latest and previous inspection reports are read from the magnetic disk and displayed. At this time, if the latest inspection report is not recorded on the magnetic disk, only the previous report is displayed.

If the patient ID corresponding to the input patient ID is not found in the correspondence table in the search for the patient ID, all the test IDs of the tests received by the patient are searched from the patient information stored in the database. Images, reports and study lists for all study IDs of the retrieved patients are searched in a database and the information is transferred to a workstation and stored. At this time, for all the tests, the test ID, test date, modality,
The part, the interpretation result, and the patient ID are extracted and displayed. Select the latest test and the previous test from the displayed information. The selected image ID and image data of the latest and previous inspections are extracted from the magnetic disk, and the extracted image data is subjected to data decompression processing and displayed. At this time, the inspection date is also displayed.
The image ID of the displayed image, the examination ID, and the number of the display on which the information is displayed are stored. Next, the latest and previous inspection reports are read from the magnetic disk and displayed. At this time, if the latest inspection report is not recorded on the magnetic disk, only the previous report is displayed.

The image displayed by the above steps is subjected to some processing such as moving, deleting, enlarging, gradation processing, C
When performing processing such as AD and overlay entry / display, the processing is performed as follows. For example, when a process for overlay entry is performed on a desired image, the process is performed as follows. (FIG. 9).

For this processing, there are provided a memory for storing image processing parameters or data for overlay entry corresponding to the region of interest of the diagnosis site, and an input member for designating the region of interest. As the input member, a push button provided corresponding to the region of interest, a touch panel, a mouse for designating a menu displayed on a display, or the like is used. In such an apparatus, first, a display for displaying an image to be processed is designated. At this time, the designated display displays all of the examination ID and the patient ID of the image displayed on this display. Inspection ID required from displayed ID
Or, search for the patient ID and specify it. This allows
An image corresponding to the designated ID is read from the magnetic disk and displayed. Next, a region of interest is specified by the input member. Thereafter, the processing content to be performed on the designated and displayed image of the region of interest is designated. As a result, the processing parameters corresponding to the processing to be performed on the specified image are read from the memory, and the processing is performed on the image using the processing parameters.

If the processing content is overlay entry,
The overlay entered according to the above-described overlay processing is displayed, and the overlay data is stored.

When measuring the size of a predetermined portion of the region of interest based on the displayed image, the following processing is performed.

When an operator touches any two points on the surface of the touch panel provided on the display screen on which the region of interest is displayed, for example, points A and B, the X and Y coordinate data of points A and B are changed. The data is sequentially output to the CPU from the controller connected to the touch panel.
The CPU analyzes the X and Y coordinate data of points A and B separately input according to a program stored in advance,
It recognizes that the two X and Y coordinate data indicate different positions, and determines the input coordinate data as a measurement command. In accordance with this determination, the CPU displays a scale pattern connecting the points A and B on the display. The distance between the two points can be measured by the displayed scale.

When the touch position, for example, the point A is moved,
With this movement, the X and Y coordinate data of point A are updated and input to the CPU. At this time, the CPU moves the scale so as to follow the movement of the point A. As described above, the scale is moved as the touch position is moved based on the scale displayed first, and the scale information is rewritten according to the movement.

The image is subjected to the specified processing as described above,
When the display position of the image is determined and the image is displayed at the determined position on the display, the correspondence table including the image ID, the examination ID, and the display number is updated. Also,
At this time, it is determined whether to register the processed image. When registering, the registration button is pressed. This allows
A new image ID is issued. Next, a processing image registration request is made to the database. The database registers the processed image according to a predetermined registration method in response to the registration request.
If no registration is made, no operation is performed.

Database In this database, all lists are stored in the IC memory 38. Image data, overlay data, and report data are stored on the hard disk 31. Image data input from the modality 11 and the digitizer 12 are losslessly compressed and written to the hard disk 31. There are two hard disks, one for backup.

When the hard disk is full and new data cannot be written, the old test date data is read from the hard disk, written to the optical disk 32, and the old data is erased from the hard disk. At this time, the image data may be irreversibly compressed and written to the optical disk 32. When the optical disk is full, old data is stored in the optical disk 6 of the remote database.
1 or the optical disk of the database 13 may be replaced with an optical disk of a remote database.

When information is written in the memory of the database, the address of the list in the IC memory is changed each time the location of the three types of data changes. In the case of a search, the search is performed by a search circuit 39 provided exclusively.

Next, registration of search data, preparation for image interpretation, registration of a report, request of a report, and registration of an overlay and a processed image performed in the database will be described.
