Abstract

PURPOSE:To execute a multi-frame display and photographing which can be operated easily, by registering one frame which has brought plural pieces of images to a multi-frame display, together with a data for showing an actual image, and a data for showing an element related to a two-dimensional expanse of a digital image or an element related to a variable density level of the digital image. CONSTITUTION:A CT image input part 1 inputs a CT image of a body to be inspected, and brings it to a file registration in an external storage part through an image processing part 2. A window setting processing is executed by displaying one CT image as an actual image on a monitor 4 by an operator, observing this display image (actual image) and setting desired window width WW and window level WL to the actual image, and allocated to a prescribed block of the monitor 4. Accordingly, one frame of the multi-frame display which has been registered once can be called again by the same window setting condition (W, L), therefore, the multi-frame display and photographing by the same window setting condition (W, L) can be executed again and again.

Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention provides an X-ray computed tomography apparatus 1
(XIICT Apparatus) This invention relates to an image processing and display apparatus that processes and displays digital images such as grinning images.

(Prior Art) In a digital image, the X and Y axes indicate two-dimensional spread, and the Z axis indicates II level. For example, in a CT image obtained as a digital image with an XIICT device,
The X-ray absorption coefficient corresponds to the gray level according to the two axes, and here, CTflll reflects the xta absorption coefficient over a wide range, so the CT value l! The II setting facilitates discrimination of a desired region.

Normally, the means for realizing such a function is called a window setting means, and this window setting means allows one X
Line CTlff! Images with good contrast can be obtained independently for each object of interest in the shadow.

In addition, clinically extremely useful information can be obtained by enlarging or statistically displaying only a certain object within one frame of CTI. Usually, the means for realizing such a function is called a region of interest setting means, and this region of interest setting means can independently enlarge or statistically display images of each object of interest in a single X-ray CTIII shadow. It can be obtained by

Here, the region of interest setting means is the X of the digital image.

The window setting means is related to the two-dimensional spread along the Y-axis, and the window setting means is related to the gray level of the digital image along the Y-axis. Both means are functions of the image processing display device of the CT device. .

In addition, as a function of the image processing display device of the CT apparatus, there is a multi-frame display means for displaying a plurality of CT images on the same monitor surface.

This multi-frame display is clinically extremely meaningful because it allows multiple images with different region of interest settings or multiple images with different window settings to be observed within the same field of view. Furthermore, this multi-frame display is achieved by taking multiple images with different region of interest settings or multiple images with different window settings on the same film using a camera called an imager or multi-format camera. will also be realized.

The above-described conventional image processing display device for a CT apparatus has the following problems when, for example, a plurality of images with different window settings are photographed in a multi-frame display. In other words, set the desired window settings (window width WW, window level WL) for each frame, check them visually while displaying each frame on the monitor, and then shoot the multi-frame display image with the camera. was.

In this case, the above multi-frame display image may be needed at another time, but in that case, the process of setting the desired window for each frame is repeated in the same way as above for the frame that was the current image. It was necessary and took a lot of effort.

(Problems to be Solved by the Invention) The problems to be solved by the present invention based on the above-mentioned conventional techniques are related to the two-dimensional spread of a digital image along the X and Y axes, such as setting different regions of interest. For example, when displaying multiple images with different window settings related to the Y-axis density level of the digital image, or displaying multiple images with different window settings,
Multi-frame display requires setting conditions for each frame for each Il shadow, which is very time-consuming.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an image processing and display device that is easy to operate and enables multi-frame display and Il shadow.

[Structure of the Invention] (Means for Solving the Problems) The present invention is characterized by taking the following measures in order to solve the above problems and achieve the object. That is,
One or more digital images are the current image, and multiple images are generated from the current image by factors related to the two-dimensional spread of the digital image, or the above image is generated by factors related to the gray level of the digital image. In an image processing display device in which a plurality of images generated from the images are displayed in a multi-frame manner on a monitor and a camera is capable of displaying and photographing the multi-frame images, one frame of the multi-frame display of the plurality of images is shown as the current image. The apparatus is provided with means for registering data together with data indicating an element related to the two-dimensional spread of the digital image or an element related to the gray level of the digital image.

(Function) By taking such measures, one frame that is a multi-frame display of multiple images, data indicating the current image, and elements related to the two-dimensional spread of the digital image or the shading of the digital image Since the data indicating the elements related to the level is registered, one frame displayed in multi-frame based on this registration is displayed in multi-frame on the monitor, and the multi-frame display can be photographed by the camera.

(Embodiment) An embodiment of the present invention, which targets a CT image obtained by an X-ray CT apparatus, will be described below with reference to the block diagram shown in FIG. 1 and the processing flowchart shown in FIG.

In FIG. 1, the CT image (2) input unit 1 is connected to a C
