The collected data A is subjected to analysis processing in a CPU 4. This data is stored in the memory 5 for displaying the processed images. The image data B under collection from the memory 3 is displayed on the display device 8 and the image data subjected to the analysis processing in the CPU 4 is displayed from the memory 5 by the selection of the memory selecting switch 7 while the data A is processed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nuclear medicine data processing device, and particularly to a technique for displaying both collected data and processed data on one display device.

[Prior art]

Conventional 5 In nuclear medicine data processing, it is important to monitor whether accurate image data is obtained at the time of data collection. After processing in U), an image display device for displaying the results was separately prepared.

The image display includes a display for monitoring collected data and a display of results processed by the CPU, such as a cine mode display of the heart, a left ventricular contour extraction display, and the like.

[Problem to be solved by the invention]

However, the conventional technology requires a plurality of display devices, resulting in high costs and a large installation area.

The present invention has been made to solve the above problems.

An object of the present invention is to provide a compact and inexpensive nuclear medicine data processing device that displays collected data for monitoring and displays processed images resulting from processing by a CPU using a single display device. .

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a scintillation camera that detects the position of gamma rays generated in a part to be inspected, an external memory that collects and stores image data from the scintillation camera, a central processing unit, and an image data collection monitor. A nuclear medicine data processing device comprising a memory for displaying processed images, a memory for displaying processed images, and a display device for displaying accumulated data in each of the memories, a memory switcher being provided between the two types of memories and the display device, The present invention is characterized in that by switching the switch, it is possible to monitor collected data and display processed images using a single display device.

[Effect]

According to the above-described means, the collection monitor memory constantly stores collected data. The processed image display memory stores processed images sent from the CPU. Therefore, both
They are stored in the memory at any timing, and either one can be freely displayed on a single display device using a selection switch.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be specifically described using the drawings.

1 is a block diagram showing a schematic configuration of an embodiment of the nuclear medicine data processing apparatus of the present invention; FIG. 2 is a flowchart for explaining the operation of the nuclear medicine data processing apparatus of FIG. 1; The figure is a time chart 2 showing the timing of the image data collection operation and the image data processing operation.

In FIG. 1, 1 is a scintillation camera,
The position of gamma rays generated in the inspected area is converted into an electrical signal (image data of position signal). 2 is an image data collection interface, which converts the electrical signal into a digital signal. 3 is a memory for image data collection monitor, in which the output of the image data collection interface 2 is stored as is (
stored). 4 is a CPU, which performs processing such as analysis of the output data of the image data collection interface 2 and controls each section. Reference numeral 5 represents a memory for displaying processed images, in which the image data processed by the CPU 4 is stored. Reference numeral 6 represents an external memory such as a magnetic disk, in which the collected image data and the processed image data are stored. Memorized (stored). Reference numeral 7 denotes a memory changeover switch (switcher) for selectively displaying the image data being collected from the image data collection monitor memory 3 and the image data from the processed image display memory 5. The switching operation of the memory changeover switch 7 is controlled by the CPU 4. Reference numeral 68 is a display device such as a display, and reference numeral 9 is an operation console.

Next, the operation of the nuclear medicine data processing apparatus of this embodiment will be explained.

As shown in FIGS. 1 and 2, the γ-ray position signal generated from the scintillation camera 1 is sequentially stored as image data A in the image data collection monitor memory 3 and external memory 6 via the image data collection interface 2. , B, and C (steps 101, 102, 103).

Further, the image data A collected in step 101 is input to the CPU 4 and subjected to processing such as analysis (step 104). This processed image data is sent to and stored in the processed image display memory 5 (step 105).

And while the image data A is being processed.

By selecting the memory changeover switch 7, the image data B being collected from the image data collection monitor memory 3 is displayed on the display device 8, or the image data B being collected from the processed image display memory 5 is processed such as analysis by the CPU 4. Image data is displayed (step 106).

As a result, by providing the memory changeover switch 7 during image data collection, the progress of data collection can be monitored, and after one image data collection.

By connecting the memory changeover switch 7 to the processed image display memory 5, the image data processed by the CPU 4, such as analysis, can be viewed.

As shown in FIG. 3, the timing of the image data collection operation and the image data processing operation is such that immediately after the collection of image data A is completed, processing such as analysis is performed and primary image data B is collected. The patient is prepared for the test, and the image data B is collected. The processing of the previous image data may or may not be completed before the collection of image data is completed. For example, even though the collection of image data C in FIG. 3 has been completed, the processing of image data B has not yet been completed. At that time, the processing of image data C is started immediately after the processing of image data B is completed.

The present invention has been specifically explained above using examples, but
It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof.

〔Effect of the invention〕

As explained above, according to the present invention, in a system that conventionally required two display devices, the same function can be achieved with one display device, thereby reducing costs and installation space. be able to.
