Abstract

PROBLEM TO BE SOLVED: To provide a medical image display unit wherein a series of inspection images of a certain subject and the past inspection images of the subject can be easily projected for comparison. SOLUTION: A medical image display unit is provided with a plurality of CRT monitors 2a, 2b, 2c, 2d, 2e and 2f, and a series of inspection images of the day (images of the day) of a certain patient are displayed on the CRT monitors 2a, 2b and 2c. When the images of the day are displayed, the images taken previously on the same region of the patient (the past images) are retrieved automatically, and when there are past images in existence, they are displayed on the CRT monitors 2d, 2e and 2f. Since the past images are displayed automatically by only displaying the images of the day, it is possible to compare the images of the day with the past images and to read the images without instructing display of the past images. In addition, when there are no past images in existence, displays on the CRT monitors except the CRT monitors on which the images on the day are displayed are erased, and other images which were previously displayed can be prevented from being interpreted by mistake.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the medical image display apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIG. 1, a medical image display apparatus includes a plurality of CRT monitors 2a, 2b, 2c, 2d, 2e, 2f.
The CRT monitors 2a, 2b, and 2c display a series of examination images of a certain patient on the day (images on the day). When the image is displayed on the day, the previously captured image (past image) of the same part of the patient is automatically searched, and if there is a past image, it is displayed on the CRT monitors 2d, 2e, and 2f. As described above, the past image is automatically displayed only by displaying the image of the day, so that the image of the day and the past image can be compared and interpreted without giving an instruction to display the image of the past. Further, by displaying the past image on a CRT monitor other than the CRT monitor on which the image of the day is displayed, overwriting can be prevented.

When there is no past image, as shown in FIG. 2, the displays on the CRT monitors 2d, 2e and 2f are cleared. In this manner, by clearing the display on the CRT monitor on which no image is displayed on the day, it is possible to prevent the image of another patient displayed previously from being erroneously interpreted.

A CRT monitor for displaying a current day image and a past image is determined by a CRT management table 401 shown in FIG. In the figure, CRT numbers 1 to 6 are respectively CRT numbers.
It corresponds to the monitors 2a to 2f. The CRT management table 401 indicates which of the current day image and the past image is displayed on each CRT monitor. In the example of FIG. 3, images of the day are displayed on CRT numbers 1, 2, and 3 (CRT monitors 2a, 2b, and 2c), and past images are displayed on CRT numbers 4, 5, and 6 (CRT monitors 2d, 2e, and 2f). Is displayed.

FIG. 4 is a block diagram showing a hardware configuration of the medical image display device. As shown in FIG. 1, the medical image display apparatus mainly includes a plurality of CRT monitors 2.

It comprises an image processing device 7 for performing image processing, a central processing unit 8 for controlling these components and other attached devices, and a main bus 9 for connecting these components.

FIG. 5 is a flowchart showing a processing procedure of the medical image display apparatus. First, a mode for comparative image reading is selected, and based on a list of character information of the examination image displayed on the character display 4, the registration number or patient name of the image to be displayed on the same day is input using the keyboard 6 or the mouse 5. By clicking on the corresponding character information, a series of images of the day to be displayed is selected (step 30).

The CRT management table 401 is read from the magnetic disk drive 3, and it is determined whether each CRT monitor displays an image of the day or a past image (step 31). For example, images on the day are CRT monitors 2a, 2
b, 2c, and past images are displayed on the CRT monitors 2d, 2c.
e, 2f.

The first image of the day is read from the magnetic disk device 3, transferred to the image memory 1a, and displayed on the CRT monitor 2a (step 32). Similarly, 2 of the day
The image is read from the magnetic disk device 3, transferred to the image memory 1b, and displayed on the CRT monitor 2b (step 33). Also, the third image of the day is read from the magnetic disk device 3, transferred to the image memory 1c, and
It is displayed on the T monitor 2c (step 34).

When an image of the day is displayed on the CRT monitors 2a, 2b, 2c, the previous image (past image) of the same part of the patient is retrieved from the magnetic disk device 3 (step 35).

As a result of the search in step 35, if a past image exists, the first image in the past is read from the magnetic disk device 3, transferred to the image memory 1d, and displayed on the CRT monitor 2d (step 36). . Similarly, the second past image is read from the magnetic disk device 3, transferred to the image memory 1e, and displayed on the CRT monitor 2e (step 37). Further, the third past image is read from the magnetic disk device 3 and transferred to the image memory 1f.
It is displayed on the CRT monitor 2f (step 38). As described above, the past image is automatically searched and displayed only by displaying the image of the day, so that the image of the day and the past image can be compared and interpreted without the display instruction of the past image. In addition, a past image is displayed on the CR
By displaying on a CRT monitor other than the T monitor, overwriting can be prevented.

On the other hand, if there is no previous image as a result of the search in step 35, the image memories 1d, 1e and 1f are cleared, and all the displays on the CRT monitors 2d, 2e and 2f are cleared (step 39). In this manner, by clearing the display on the CRT monitor on which no image is displayed on the day, it is possible to prevent the image of another patient displayed previously from being erroneously interpreted.

In this embodiment, a case has been described in which, when there is no past image, all the CRT monitors that do not display the image of the day are cleared, but a display such as "no past image" is displayed on these CRT monitors. You may.

[0021]

As described above, according to the present invention, when the latest inspection image is selected, the past inspection image is automatically searched, and when the past inspection image exists, the latest inspection image is obtained. Is displayed on the monitor where is not displayed, the latest inspection image and the past inspection image can be compared and interpreted without instructing the display of the past inspection image. In addition, when a past inspection image does not exist, the monitor on which the latest inspection image is not displayed is erased to prevent the image from being mistaken for another inspection image displayed earlier. it can.
