Abstract

PURPOSE:To save memory capacity of a memory device by storing data to which the data of a CT picture and the data of additional information are overlapped and added by using coordinates, and selecting whether added data is displayed in a picture mode or the data of a CT picture after the substracting processing is displayed in a picture mode. CONSTITUTION:When the additional information is inputted from a character input device 1, additional information data (m) are formed by a display pattern forming routine. On the other hand, CT picture data (n) are outputted from a CT scanner 2. The additional information data (m) and a CT picture data (n) are added by a matrix adding routine, and adding data l are formed. The adding data l are stored in a memory device 4 in accordance with the matrix transfer routine and read in accordance with the necessity. When the CT picture with additional information is to be displayed, the memory data are read as they are, only the CT picture to display to a monitor 5 for display is to be displayed, and then, an AND operation processing is executed by a matrix mask routine (n) and only the CT picture is displayed.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a tomographic image (referred to as a CT image) taken by an image display device, particularly a computerized tomography diagnostic device, and its CT image.
Date and conditions for photographing the Ti1ji statue.

Name of the subject (patient) of the CT image (referred to as collateral information)
The present invention relates to a CTi1i image display device that displays on the same screen.

[Technical background of the invention and its problems] When diagnosing a subject, it is necessary to display additional information on the screen in order to identify the tomographic image of the subject. When a part of the image is missing and there is a problem with diagnosis, it may be necessary to remove additional information.

In the conventional CTi1ji image display device, 01
In addition to the storage area for image data, a storage capacity for additional information data is required, and when superimposing value information data on CT image data, the data must be read from each storage device and used by a computer. IJ requires sloppy editing work. For this reason, there is a drawback that the entire device becomes larger and more complicated.

[Object of the Invention] The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide an image display device that can save the storage capacity of a storage device and simplify data editing processing by a computer. do.

[Summary of the Invention] The present invention provides means for superimposing and adding CT image data and incidental information data, a means for storing the added data,
Subtracting the data of the additional information from the added data and performing C
It is characterized by comprising means for returning the CT image data to the CT image data, and means for selecting whether to display the addition data as an image or to display the CT image data after the subtraction process as an image, This saves the storage capacity of the device and simplifies the computer's data editing process.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an image display device according to an embodiment of the present invention, in which 1 is a character input device for inputting supplementary information, 2 is a CT scanner, and 3 is supplementary information data of the character input device 1. Input CT image data and sound from CT scanner and perform screening processing = 1 mp] - ta, 4]
a storage device 5 for storing data processed by the microcoater 3;
is a display monitor that displays an image of the data processed by the pump coater 3. Although not shown here, the character input device 1 inputs additional information data m and C.
A device for superimposing and adding the CT image data and sound of the T-scanner 2; It has a selection device for outputting or not.

Note that 16-bit data is input to the display monitor, and when the data is X'4000' (hexadecimal display) or more, it is displayed in white, and when the data is X'0OOO', it is displayed in black. And if the data is less than X'4000' then X'0001'
In the above case, the larger the data value, the closer to white the color is displayed with a density of 1.

FIG. 2 shows a 320×320 matrix memory area of the storage device 4, CTi1I! Data for displaying the entire i-image can be stored.

FIG. 3(a) is a diagram of a 4.times.57 matrix configuration of 16-bit data for displaying one character of supplementary information inputted by a character input device.

Since the additional information is text, it is 4 x 5 depending on the text
White and black data are assigned to the individual information of the 71 helices, and characters are generated on the display screen.

For example, character 11 F 1 from key 17 character input 81f1
When 1 is input, the vixel niha
'8000' wo, other nohikuse/lz niLIE
X'0000' is set. In other words, Figure 3 (

．． X'-8000° is set to rrL+72mzo, ms ~ m8, m+2, m14 ~ ffl
j[i is set to X'0000°. Figure 3 (
1)) is a pattern when the matrix shown in FIG. 3(a) is displayed on the display monitor 5.

FIG. 4 is a diagram showing a state in which the CT image data and sound supplementary information data m in the P area of FIG. 2 are added, and the added data A is stored in the P area of FIG.

Next, the operation of the embodiment will be explained with reference to the flowchart shown in FIG. When additional information is input from the character input device 1, additional information data m is created by a display pattern creation routine. On the other hand, from CT scan 2, CTi
1ji image data n is output. Additional information data m,!
:The CT image data n is added by the matrix calculation, and the added data ((Fig. 4) is created.The data of 1 at this time = 5-5 is as follows.For example, n5 of cTimil data
is X'0O1F and n6 is X'04FC', then ms of the additional information data (character E) is X'8000
' and ms is x'oooo' r Alcala, J
6 = n5 + m5-X'001F'ORX'
8000'-X'801F' 1! a = na + me = X'04FC' OR
X'0000'-X'OiC' roar.

This addition data 1 is stored in the storage device @4 according to the matrix transfer routine, or read out as necessary. In this way, the storage device 4 stores CT image data N and supplementary information data m superimposed on each other. Therefore, when it is desired to display both CT images with attached information, the stored data can be read out as is and displayed on the display monitor 5. That is, when the data subjected to matrix addition is output to the display monitor 5, j! 1st to 4th, Irs, Ils~
No. 11.113, 'j! +3, j! 17~
j! All of the values are X'8000' or more, so they are displayed in white, while 16~Ie, 112°I! 14-116
Since it is directly displayed as a CT value in gradation, it means that it is displayed in a superimposed manner.

When it is desired to display only the CT image, logical product processing is performed using a 7-trix mask routine. That is, yij AND
AND a AND X'7FFF'-X' 0
4FC'=n6. In other words, ns and no are the output data of the matrix mask routine, and
'8000' is removed and the original CT image data n5. n
6 is being played. Therefore, when this data is displayed on the display monitor 5, only the CT image is displayed.

In this way, since the CT image and the supplementary information are stored in the same storage area, storage capacity can be saved, and editing and separation in the case of superimposed display can be simplified.

[Effects of the Invention] As described above, according to the present invention, it is possible to save the storage capacity of a storage device, and there is no need to read data from multiple storage devices and perform complicated editing processing. ~ can be achieved.
