Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to an image display device used in a medical imaging device such as an X-ray CT device, and in particular to an image display device used in a medical imaging device such as an Concerning improvements in switching technology.

(Prior art) Conventionally, when performing an image search to switch the displayed image on the display in this type of image display device, a function key dedicated to image search is used, or a function key associated with supplementary information for each image on the display is used. Images were searched interactively by displaying a list of additional information.

(Problem to be Solved by the Invention) However, in any of the above methods, a certain degree of skill is required from the operator because a complicated operation must be performed to switch the displayed image on the display. . Particularly, in a CT apparatus having only one display, the screen must be switched from image display to directory display each time, resulting in a more complicated operation.

The present invention has been made in view of this situation, and its purpose is to provide an image display device that can instantly switch to a desired display image with a simple operation.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides reading control for a system file storing a plurality of images and supplementary information for each image. and a display control unit that controls displaying an image selected by the image processing and accompanying information of the image on a display, and the display control unit includes a display control unit that controls displaying a selected image and accompanying information of the image on the display, and the display controlling unit includes a The present invention is characterized in that it includes an image display switching means that performs control to selectively display an image indicated by specified specific information each time an operation for specifying information is performed.

(Function) With the configuration of the image display device according to the present invention, if the operation of specifying only specific information from among the incidental information on the display is performed using a pointing device such as a mouse, for example,
Reading out the image indicated by the designated specific information from the system file and displaying it on the display can be achieved by the image display switching means of the display control section.

(Embodiment) FIG. 1 is a block diagram showing the functional configuration of an image display device to which the present invention is applied.

The image display device has two storage areas: an image storage area 1a for storing a plurality of images in a system file 1, and an image information table 1b for storing supplementary information for each image. A display control unit 2 that performs reading control for the system file 1 and a display 3 that displays an image 1a selected from the system file 1 and additional information 1b of this image by the readout control of the display control unit 2 are basically configured. We are preparing for

Furthermore, the display control unit 2 is configured to display the image 1a on the display 3.
Every time an operation is performed using the mouse 4 to specify specific information from the accompanying information 1b displayed together with the mouse, the image to be displayed next in the image information table 1b of the system file 1 is selected based on the specified specific information. It has a function as an image display switching means 5 that performs a search, selects the searched image from the image storage area 1a, and controls displaying it on the display 3. In addition to this image display switching means 5, it also functions as an additional information updating means 7 that performs control to update and display part or all of the additional information for each image on the display 3 in response to operations on the keyboard 6. It is something that has both.

In the above, the system file 1 is an external storage device such as a magnetic disk device. The image data 1a on this system file 1 is matrix data, and the image information table 1b stores ID codes, patient names, table positions, etc. as additional information. The mouse 4 has a switch 4a.

4b, and a switch 4a for raising or lowering the cursor on the display 3.

4b is preset for ascending/descending. Note that instead of the configuration that uses the mouse 4, a configuration that uses a light pad or a touch panel can be adopted.

The first embodiment of the image display device of the present invention equipped with such various parts has a patient ID number (ID-N
This is a case where image search is performed using (o). This first embodiment will be explained with reference to FIGS. 2 to 4.

As shown in Fig. 2, with the patient ID number displayed together with the image on the display 3, move the cursor using the mouse 4 to select the patient ID as shown in Fig. 3(a).
When the cursor is moved to the position of number D and clicked at the position of the cursor, the patient ID number can be entered as shown in FIG. 3(b).

After ensuring that the patient ID number can be entered in this way,
When the patient ID number to be searched is entered on the keyboard 6 as shown in FIG.
An image corresponding to the input patient ID number is displayed as shown in Figure (b). Note that since many images are usually stored in system file 1 for each patient ID number, the display status of the first image is obtained first, and the corresponding image is updated each time the return operation is performed. It will be done.

The second embodiment is a case where an image search is performed using patient name and photographing date among the incidental information. This second embodiment will be explained with reference to FIGS. 5 to 7.

As shown in Fig. 5, while the patient ID number is displayed together with the image on the display 3, use the mouse 4 to move the cursor and move the cursor to the position of the patient's name as shown in Fig. 6(a). When the cursor is moved and clicked, the patient's name can be entered as shown in FIG. 6(b).

After ensuring that the patient name can be entered in this way, enter the patient IN number corresponding to the patient you want to search on the keyboard 6 as shown in Figure 7(a), and then enter the imaging date as shown in Figure 7(b). When inputted as shown in FIG. 7(c), an image corresponding to the inputted patient name and photographing date is displayed. In addition, when changing the patient to be searched, it is sufficient to repeat the content explained according to FIGS. 6 and 7. Further, when the photographing date is currently displayed, the photographing date may not be changed. If images corresponding to the input patient name and imaging date are stored in the system file 1 as a plurality of image groups (EXAM), it is preferable to display the latest one.

Here, on the display 3, if there is another image of the same object, the presence of this image is known, for example, rNEXT.
If you display J as shown in Figure 8, each time you click "rNEXT" with the mouse 4 when the search image is different, the next image will be displayed as shown in Figures 9 (a) and (b). They are selected based on this relationship. Then, when the target search image is displayed, it is preferable to click rENDJ to end the image search.

For this reason, according to the first and second embodiments of the present invention, image retrieval can be easily accomplished by simply specifying additional information on the display 3. Of course, the present invention also covers the above first and second aspects.
The image search is not limited to the embodiments, and the image search can be performed using various methods listed below.

(1) A method of image searching using the presence or absence (+, -) of contrast enhancement (CE) displayed on the display as additional information.

In this method, when pointing to CE+(-), if there is an image of CE-(+) at the same slice position of the same examination of the same patient, that image is displayed on the display.

(2) A method of image searching using the slice position (Table-Position) displayed on the display as supplementary information.

This method yields images of different slice locations of the same CE of the same examination of the same patient. That is, an image at the minimum slice position larger than the currently displayed image or an image at the maximum slice position smaller than the currently displayed image is displayed on the display.

(3) A method of image searching using the slice number (scanning order) displayed on the display as additional information.

This method outputs an image obtained by scanning one image before or after the image being displayed.

(4) A method of searching for images using the scan time (information indicating when the scan was performed) displayed on the display as additional information.

This method is operated in the same manner as the method (3) above. However, this may be used only in dynamic CT, and may be limited to images at the same slice position.

(5) A method of image searching using patient ID, patient name, and directory number displayed on the display as additional information.

This method displays images of another patient examined on the same day on the display. Displays images of the next or previously examined patient. Alternatively, a pop-up menu may be displayed on the display and the operator may make a selection from the pop-up menu.

(6) A method of image searching using a reconstruction function or image filter number displayed on a display as supplementary information.

This method outputs images reconstructed using other functions, if any. Otherwise, a pop-up menu may be displayed on the display, and the operator may manually select which function or image filter image is desired from the pop-up menu, and then create that image.

(7) A method of image searching using the detection port displayed on the display as additional information.

This method produces images of different examinations of the same patient.

Generally, in many cases, the same patient is not tested multiple times in a day. In this case, the image to be displayed is located on a file device (such as an optical disk) or an external file server device (connected via a network). Therefore, the image stored in the file device or the like is called up and displayed.

(8) A method of image retrieval using the X-ray technique (KV, mA, scan speed, slice thickness) displayed on the display as additional information.

This method displays images of the same slice of the same patient scanned using other techniques, if any.

(9) Image observation direction (View-From-Feet, V
iew -From -Head).

In this method, when one of the image observation directions is specified, the corresponding image is displayed with the image horizontally reversed.

(10) A method of image searching using the tilt angle displayed on the display as additional information.

This method yields images of the nearest slice scanned at different tilt angles.

[Effects of the Invention] As explained above, according to the present invention, a desired image can be selected and displayed on the display simply by performing an operation of specifying specific information from the accompanying information displayed together with the image on the display. Therefore, it is possible to quickly switch displays that are effective for diagnosis with simple operations.
