Abstract

PURPOSE:To surely and simply display the clear picture of a desired area by storing the picture processing parameter of the desired area in advance and processing the picture of the selected desired area with the picture processing parameter. CONSTITUTION:A desired area on a screen is select-indicated with pressing buttons for selecting 9a and 9b. The information ofthe selected desired area is inputted to a multi-display control system (MDS) 5 and is read by a CPU 1. The CPU 1 detects the picture processing parameter of multilevel processing, frequency processing and so on within a memory part 2 to correspond to the input information. Moreover, the CPU 1 sets the picture processing parameter within an image memory (IM) 3 to the picture processing parameter to correspond to the input information and transmits the picture data of the desired area to be processed from the IM 4 to an image processor (IP) 3. The IP 3 processes the picture data by the picture processing parameter and the processed picture data are returned to the IM 4. Then, the CPU 1 transmits the processed picture data to the MDS 5 and makes a CRT 6 display them.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) The present invention provides a method for examining patients by using an electronic display device such as a CRT to take images taken by a medical image diagnostic apparatus. The present invention relates to a medical image display device for displaying images.

(Prior Art) Conventionally, in this type of medical image display device, image processing, such as window processing, has been performed in order to make the image of the region of interest clearer and easier to see.

This is because the contrast of CRT is low, so when viewing a chest X-ray image of a patient, for example, it is difficult to see the lung fields and mediastinum, which have different brightness and contrast, at the same window level of brightness. In other words, when the window level is adjusted to the lung field, the mediastinum becomes invisible, and conversely, when the window level is adjusted to the mediastinum, the lung field becomes invisible, so it was necessary to change the window level as appropriate depending on the region of interest.

(Problem to be Solved by the Invention) However, in the conventional medical image display device described above, the window level is changed for each region of interest using an operation button, a mouse, etc. Since it was necessary to search for a clear state, the problem was that the work was complicated and time-consuming.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a medical image display device that can easily obtain a clear image of a region of interest.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention includes an image display means for displaying a medical image and a region of interest of the medical image displayed by the image display means. a region of interest selection means for
The apparatus includes a storage means for storing image processing parameters for processing the image of the selected region of interest, and an image processing means for processing the image of the region of interest based on the image processing parameters.

(Function) In the present invention, the storage means in which image processing parameters for processing the image of the selected region of interest are stored in advance, and the image processing means for processing the image of the region of interest using the image processing parameters are provided. By simply selecting a desired region of interest using the region selection means, an image of the region of interest subjected to image processing is displayed by the image display means. In other words, a clear image of the region of interest can be easily obtained with a one-touch operation.

(Embodiment) An embodiment of the medical image display device of the present invention will be described based on FIGS. 1 to 3. Figure 1 is a professional diagram of the medical image display device, Figures 2 (a) and (b) are perspective views of the operation panel for selecting the region of interest, and Figures 3 (a) and (b) are the An explanatory diagram of area selection means is shown.

That is, as shown in FIG. 1, the medical image display device has the following features:
A central processing unit (CPU) 1 and a memory unit (MEM) 2 in which image processing parameters corresponding to regions of interest such as the lung field or mediastinum are manually stored are provided, and these CPUI and MEM
2, an image processor (IP) 3, an image memory (IM) 4 connected to a high-speed bus, and a multi-display control system (MDS) 5 are connected in parallel. The MDS 5 is connected to a CRT 6 and an input section 7 into which information for selecting a region of interest is input. The input section 7 is, as shown in FIGS. 2 and 3, an operation panel 9 or a CRT on which a plurality of selection coppers 9a and 9b are formed, on which regions of interest are displayed in letters or figures.
There is a touch panel 10 that displays a plurality of regions of interest as characters or graphics on the screen of 6, or a touch panel 10 that displays a plurality of regions of interest as characters or graphics on the screen, and a mouse 11 that selects and instructs a desired region of interest that is displayed as a plurality of characters or graphics on the screen.

Next, the operation of such a medical image display device will be described.

First, select copper 9a or 9 on which the desired region of interest is displayed.
b, or by pressing the touch panel 10 or using the mouse 11 to select and instruct a region of interest on the screen. As a result, information on the selected region of interest is input to the MDS 5. The information entered is recognized and stored by the MDS5. After that, MDS5 interrupts the CPUI and MDSS
The input information within is read by the CPUI. after that,
The CPU detects image processing parameters such as gradation processing and frequency processing in the MEM 2 that correspond to the input information. Furthermore, the CPUI sets the image processing parameters in 1M4 to the image processing parameters corresponding to the above input information, and sets the image data of the region of interest to be processed in 1M4.
to IP3. Then, IP3 processes the image data according to the image processing parameters, and the processed image data is returned to 1M4. After that, the CPUI sends the processed image data to the MDS5.

Next, the MDS 5 sends the processed image data to the CRT 6, and the CRT 6 displays the processed image of the region of interest.

[Effects of the Invention] As explained above, according to the present invention, the image processing parameters of the region of interest are stored in the storage means in advance, and the image of the region of interest selected by the region of interest selection means is determined according to the image processing parameters. The processed image is then displayed by the image display means, so that a clear image of the region of interest can be reliably and easily displayed with a one-touch operation. Therefore, the above-mentioned problems can be solved by improving workability and shortening the working time.
