Abstract

PURPOSE:To realize the two different processing of an individual processing or a processing by means of the collective processing indication of a related image as against the image of a display screen displayed by using a multiwindow only by the difference of the indication whether it is within a section or out of the section. CONSTITUTION:In a method for displaying the plural images #1-#4 and designating the object #1 to be selected among them by using a mouse 2, only the image is set to be the object when the image is cricked by the mouse at a position 2 on the image, and the image nearest to a cricked point and all the related images are set to be objects when the image is cricked on a position 3 on the external side of the image.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse-use target image designating method and processing method suitable for medical image processing.

[0002]

2. Description of the Related Art There are many examples in which a plurality of medical images are displayed on a display screen in accordance with a multi-window, and a process is performed to display the processed image to observe the image. The processing target may be one or a plurality of medical images. For example, there are various examples such as displaying a CT image, an MRI image, and a fluoroscopic image of an adjacent region. In the former case, it is often the case that the image enlargement processing is simultaneously performed on all the images in parallel rather than individually performing the image enlargement processing. In the latter example, image enlargement processing is performed for each individual image, or one image is enlarged.
In many cases, other images are individually processed differently, such as a region of interest setting process (ROI process). The image processing includes various types of processing such as level window processing and histogram processing in addition to enlargement processing and ROI processing. Here, the level window process is a process for freely changing the display range when, for example, the CT value is plotted on the horizontal axis and the gradation is plotted on the vertical axis, as shown in FIG. The solid line is one level window LW ₁ , the dotted line is the other level window LW _2.
Indicates. The level window is designated by window widths W ₁ and W ₂ and window start positions S ₁ and S ₂ . The histogram process is a process of displaying a graph, and is used for calculating and displaying the density or area of a specific CT value.

[0003]

In the display example on one screen by multi-window, the image processing is performed by using the mouse. That is, in image processing of an individual image, the image processing is executed by instructing the individual image with the mouse cursor and also instructing a menu of processing contents. When the same image processing is performed on all the images in the multi-window, the individual image processing is performed while sequentially instructing each image.

When performing the same image processing on a plurality of images displayed in such a multi-window, the worker needs to give instructions for the number of images. There is an example in which as many as 16 images are displayed on one screen by multi-window when the number is at least four, and the work amount becomes a burden as the number of images increases.

An object of the present invention is to provide a mouse-use target image designating method and processing method which enables processing of all images by processing similar to individual processing of images displayed in multi-window.

[0006]

The present invention is a method of displaying a plurality of images and designating an object to be selected from among them by using a mouse. When the mouse cursor is clicked on the image, only the image is targeted. Then, when the user clicks on the outside of the image, a target image designating method is disclosed in which the image closest to the clicked point and all the images related thereto are targeted. Further, a method for processing the target image according to the processing menu will be disclosed.

[0007]

According to the present invention, when the mouse cursor is clicked on the image, only the image is targeted, and when the mouse is clicked outside the image, the image closest to the clicked point and all the related images are targeted, and individual Image processing of all images can be instructed by the same instruction as image processing. Further, according to the present invention, image processing is performed according to this target image processing menu.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of displaying four images by dividing one screen into four by multi-window. The effective display surface of one display screen 1 is equally divided into four and four CT images # 1 to # 4
Is displayed. In the present embodiment, when the mouse cursor 2 is moved to a section in which the image # 1 is displayed on the display screen 1 and clicked, the individual processing of the image # 1 can be instructed. On the other hand, as shown by the mouse cursor 3, when the mouse is moved to the vicinity of the outside of the divided area of the image # 2 and clicked, the same image processing of all other display images related to the image # 2 can be instructed. .

The other display images related to # 2 are the other three images # 1, # 3 and # 4 in FIG. Further, for these processes, it is necessary to display a menu for image processing on a part of the screen or another screen and select and instruct one of them.

All the above processing contents can be realized by software. FIG. 3 shows a processing flowchart, and FIG. 4 shows an example of the image processing menu set on the memory table 4.

In FIG. 3, it is first checked whether or not the mouse is clicked outside the divided section (flow 20). If it is a click on the outside, the process proceeds to step 22, and if it is a click inside the section, the process proceeds to step 21. In step 22, the image processing menu as shown in FIG. 4 is displayed, and one of them (one of enlargement and ROI processing) is selected and instructed. The image of the closest division to the image processing according to the instructed processing content (# 2 in FIG. 1)
(Step 23). Further, in step 24, the same processing is performed on all related images. Although all the related images are all the remaining images in FIG. 1, some of the remaining images may be used. Whether or not the image is a related image may be registered in the table.

In step 21, it is checked whether or not a click has been made in the section. If it is a click in the section, the process moves to step 25 to display the menu shown in FIG. 4 and to select and instruct one of them. Next, at step 26, only the clicked image is processed according to the instruction content.

FIG. 5 is a diagram showing a computer processing system of the present invention. CPU 6 is main memory 7 or magnetic disk 8
3 is realized according to the program of FIG. The magnetic disk 8 stores various images to be multi-windowed, and the CPU 6 stores these images in the main memory 7.
Then, the multi-window processing is performed to temporarily store the image divided by the multi-window in the display memory 9. The contents of the display memory 9 are sent to the CRT 10 for multi-window screen display. A table 4 (FIG. 4) showing image processing contents is set in the main memory 7, and the mouse 1
2 or the display memory 9 read out by an instruction from the keyboard 14
It is temporarily stored in the CRT 10 and then displayed on a part of the screen of the CRT 10. Further, the controller 11 is used for input of the mouse 12, and the controller 13 is used for input of the keyboard 14. Further, the common bus 15 establishes a common connection with the CPU 6 and the like.

According to the embodiment of FIG. 5, steps 20 and 21 can be executed by the operation of the mouse 12 through the controller 11 to determine whether the CPU 6 is an outer click or an inner click. Steps 23 and 25 are
The operation of the mouse 12 is controlled by the CPU 6
Can be executed by reading out the contents of the table 4 and displaying it on the CRT 10 and pointing this with the mouse cursor. Steps 24 and 25 can be executed by the CPU 6 reading the processing content designated by the mouse cursor and processing the menu.

[0015]

According to the present invention, two different processes, that is, an individual process or a process by a common collective instruction of related images, are performed on an image on a display screen displayed in a multi-window.
It can be realized only by the difference in the indication of whether it is within a division or near a division, and the image processing operation is simplified.
