DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The image display device shown in FIG. 2 is incorporated in, for example, the image interpretation workstation described above. While this image display device controls the entire device,
A central processing unit (hereinafter, referred to as CPU) 1 that controls image selection for multi-frame display is provided. This CPU
An image disk 2 storing image data is connected to 1 via a bus structure, and an input device 3, a display device 4 and a general-purpose memory 5 are connected via a bus structure.

The image disk 2 stores medical image data of the inside of the subject obtained by modalities such as an X-ray diagnostic apparatus, an ultrasonic diagnostic apparatus, and a magnetic resonance imaging apparatus. The input device 3 has a mouse, a keyboard, a touch panel, etc., and the change key 3 is provided in the keyboard.
a and a numeric keypad 3b. Display device 4 is CR
It has a T display and a circuit for displaying the supplied digital image data on a CRT display.

Further, in the bus structure connected to the CPU 1,
The image processor 6 and the large screen memory 7 are connected. The image processor 6 takes charge of specialized image processing such as data rearrangement at the time of list display and sort processing. At the time of the image processing, the image data of the image disk 2 is loaded into the large screen memory 7.

The CPU 1 reads out a system control main program stored in advance in the general-purpose memory 5 to control the entire system, and if necessary, executes a list display and image selection subprogram in the multi-frame display shown in FIG. Read and start this subprogram.

Next, the contents of the subprogram shown in FIG. 3 will be described as the operation of the embodiment. When the operator uses the input device 3 to perform an operation to perform multi-frame display, the multi-frame display is determined by the processing of the main program, and the sub-program in FIG. 3 is activated.

When this subprogram is activated, preset information of the identification display body is read from the general-purpose memory 5 to the work area in step 10 of FIG. Where identified
The display object is displayed as an image list as described later.
Display one or more of the group the index of the image that
Say the identification element to do.

The identification display body is used for displaying an image list in multi-frame display. The multi-frame display is usually indexed by the shooting date and patient name.
Group the images as meters) ,
A plurality of images belonging to the group are displayed at the same time. The present invention divides the index into groups (i.e., it is structured into groups).
Hisage image list for image selection using the Uni) identification member
The principle is to show .

The identification display body in this embodiment is a line thicker than a normal ruled line, and the information of this thick line is preset.

Next, the CPU 1 advances the processing to step 11, and the preset value of the display unit is read from the general-purpose memory 5 to the work area. This preset value is input from the keyboard when the system is started.

The display unit is the number of images in one frame in multi-frame display, and the preset value of the display unit in this embodiment is "4". The preset value can be set, for example, from a minimum "1" to a maximum "16".

Then, the process proceeds to step 12, where the CPU 1
Instructs the image processor 6 to display a list. As a result, the image processor 6 calls the index (that is, the ID number, the shooting date, the time, etc.) of the image data from the image disc 2 into the large screen memory 7. Then, the retrieved index data is rearranged, and an image list is created by dividing each preset value of the display unit (here, “4”) by a thick line, and the image list is displayed on the CRT display of the display device 4. As a result, the CRT display is shown in FIG.
The image list as shown in is displayed.

Next, in step 13, the CPU 1
Attempts to read a signal from the change key 3a of the input device 3. Then, in step 14, step 13
It is determined whether or not the operator is going to change the display unit based on the signal value read in. In the determination in step 14, NO (that is, the display unit is not changed,
If it is determined that the preset value is “4”, the process of steps 15 and 16 is performed.

At step 15, an image is selected from the ten-key pad 3b of the input device 3, that is, an attempt is made to read the selection information of the index of the desired image. In step 16, it is determined based on the read information in step 15 whether the operator has selected an image. If the determination in step 16 is NO (that is, image selection has not yet been performed), the process returns to step 13 and waits while repeating the processes of steps 13 to 16.

During this waiting, the result of the judgment in step 16 is YE.
If S (namely, the index of the image is designated by the operator from the ten-key pad 3b), the processes of steps 17 and 18 are subsequently performed.

In step 17, the CPU 1 commands the image processor 6 to select an image. As a result, the image processor 6 selects an image in the group to which the image instructed by the operator belongs. For example, as shown in FIG. 5, in the image list divided into image data groups of four sheets each with a thick line, NO. If the image index No. 6 is selected, the image processing processor 6 determines that the NO. All images in the group to which the image index of No. 6 belongs, that is, NO. Four images with image indexes 5 to 8 are combined and selected.

Furthermore, in step 18, CPU 1 instructs the multiframe Display image in the image processor 6. As a result, the image processor 6 performs the step 1
The four images selected in the process of 7 are displayed on the CRT display in multiframe as shown in FIG. 6, for example.

On the other hand, it is assumed that the determination of YES is made in step 14 while waiting while repeating the processing of steps 13 to 16. That is, the operator changes the key 3
This is a case where the display unit of multi-frame display is changed by pressing a (the state at that time is shown in FIG. 7). in this case,
Then, the process proceeds to steps 19-21.

At step 19, an attempt is made to input a change value of the display unit (that is, the number of images in the group forming the multi-frame display) from the ten keys 3b. Step 20
Then, it is determined whether or not the display unit change value has been input in the reading in step 19. And step 2
When it is determined to be 0 (YES to input the change value of the display unit), the process of step 21 is executed, the preset value up to that point is updated to the change value, or the display unit that has already been changed is changed again. It

When the display unit is changed, the CPU 1 returns the process to step 12, displays the image list in the updated display unit, and then repeats the above-mentioned process. That is, if the display unit is not changed again, step 1
The processing of 5 to 18 is performed, and the multi-frame display is performed in the changed display unit. The same applies when the display unit is not changed from the preset value. FIG. 8 shows an image list in which the display unit is changed from the preset value “4” to “9”. According to this, the nine lines are separated by a bold line for each index.

In this embodiment, the display device 4, the image processor 6, the large screen memory 7 and the general-purpose memory 5,
In addition, the processing of steps 10 to 12 in FIG. 3 constitutes the list display means of the present invention. The input device 3 and the processing of steps 13, 14, 19 to 21 in FIG. 3 constitute the changing means of the present invention. Furthermore, the image disk 2 and the processing of steps 15 to 17 of FIG. 3 constitute the selecting means of the present invention, and include the display device 4, the image processor 6, the large screen memory 7 and the general-purpose memory 5, and step 18 of FIG. This processing constitutes the image display means.

Since the image list is processed as described above in this embodiment, the image list is clearly separated by a bold line as an identification display body for each structured group, that is, for each display unit of multi-frame (see FIG. 4). , The discrimination is improved. Therefore, just by looking at the image list, the number of images displayed in a multi-frame on one screen and the range of the image group can be recognized, there is no hesitation in the subsequent image selection, and a series of preparation operations can be performed smoothly. Further, if it is desired to change the display unit, it can be easily processed by key operation before performing multi-frame display (see FIGS. 7 and 8). For these reasons, the operability in multi-frame display is significantly improved as compared with the conventional one, the operational burden on the operator is reduced, and the versatility of the apparatus is high.

On the other hand, in the image selection while viewing the image list, regardless of which image index in one structured group is designated, all the images belonging to that group are simultaneously displayed in multiframe (FIG. 5, FIG. 5). 6). Therefore, unlike the conventional case, it is not necessary to individually specify all the images to be displayed in the multiframe while viewing the image list. As a result, the number of image selections is significantly reduced, the selection time is shortened, and the overall operation efficiency is improved. Further, since the image list is structured from the beginning, the display time itself is shortened.

The identification display bodies in the present invention are not limited to the thick lines described above, and various identification display bodies shown in FIGS. 9 to 11 may be used. In the image list in FIG. 9, the background color of the first structured group is red, 2
The background color of the third group is blue, the background color of the third group is yellow, and the color of the identification display is changed for each group. In the image list of FIG. 10, different mesh patterns such as diagonal lines and cross diagonal lines are identified and displayed for each group. Further, in the image list of FIG. 11, spaces as identification display bodies are inserted line by line between groups.

Further, in the above-mentioned embodiment, only the display unit can be changed on the way and the identification display itself remains preset. However, this identification display can also be changed from a preset thick line to a mesh pattern, for example. May be programmed to
