Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an image table 7Ji device, and in particular, an image display that displays an image of an organ with periodic motion, such as the heart of a subject, in three-dimensional animation. Regarding equipment.

[Technical Background of the Invention and Problems Therewith] Conventionally, when diagnosing the heart, for example, image data regarding the heart is collected using an X-ray CT device, a magnetic resonance imaging system (MRI), or the like. This data collection is performed for multiple slices of the heart, and data collection for multiple phases of one heartbeat cycle is performed for each multiple slice of the heart by making full use of a method using ultrafast transport technology or an electrocardiogram. The above-mentioned large amount of data obtained in this way is reconstructed by an image data processing device for each slice of the heart and for each different phase of one heartbeat cycle in each slice. The image data is ultimately stored in a storage device. The tomographic image data stored in the storage device is read out as tomographic image data for one heartbeat cycle arranged in phase order for one slice according to a display command from a doctor, and only one slice image is displayed as an animation on one screen of the display device. be done.

Therefore, the doctor can only observe the displayed one slice image at a time, but when specifying and displaying another slice, the previous slice image disappears from the screen, so the doctor can observe the heart's movement at multiple slice positions. It became difficult to make comparisons, and it was difficult to determine the degree of expansion of the diseased area and the conduction of impulses, leading to a decrease in diagnostic viscosity and diagnostic efficiency for heart disease.

[Objective of the Invention] An object of the present invention is to improve the diagnostic accuracy of heart disease by making it possible to display animation images of different slices of organs such as the heart that undergo periodic motion on the same screen of a display device. The present invention also provides an image display device capable of improving diagnosis efficiency.

[Summary of the Invention] In order to achieve the above object, the present invention collects ii!i image data at multiple 111 different phase points for at least one period for each slice of a subject with periodic motion. The image data is collected at 1A, and the image data output from this image data collection device is collected at a plurality of different phase points of at least one period for each slice. A central processing unit that creates I-image data, a storage device that stores the plurality of tomographic images output from the central processing unit, a keyboard operating device that provides an image display command to the central processing unit, and the keyboard operating device. When the display command is given to the central processing unit from , the plurality of tomographic image data stored in the storage device are synchronously supplied in a phase sequence of at least one cycle for each slice via the central processing unit. and an image display that displays the subject in three dimensions as an animation on the same display screen.

[Embodiments of the invention] An embodiment of the invention will be described with reference to the drawings.

In Figure 1, the image data collection bag @1 is equipped with ultra-high-speed transport technology, electrocardiogram utilization, etc., such as an X-ray CT device, M
It consists of an Rr device, etc., and collects image data of a plurality of different phases for one period of each slice data of an organ with periodic motion, such as the heart of a subject. The collected data is supplied to the central processing unit W12, where the data is processed to create a plurality of tomographic image data at different phase points corresponding to one cycle for each slice. These tomographic image data are stored in an external storage device such as a magnetic disk in the phase order of one cycle for each slice. These stored tomographic image data are displayed on the image display 5 by supplying a display command from the keyboard operating device 4 to the central processing @@2.
All the tomographic image data of each slice is supplied in phase order with phase synchronization between each slice. As a result, a synchronized animated composite image of each slice is displayed on the same screen of the image display 5. FIG. 2 shows how this composite image is displayed. The example shown is a case of three slices, and different slice images 7a and 7a are displayed on the same screen 6 of the image display 5.
7b and 7c are synchronized and displayed as animations.

In order to control the state of images displayed on the same display screen of the image display device 5, a superimposition degree setting device 8 and a viewing angle setting device 9, which can be operated by the keyboard operating device 4, are provided. The former superposition degree setting device 8 controls the degree of overlap of each slice image 7a, 7b, 7c displayed simultaneously on the same screen of the image display Ii5, and the latter viewing angle setting device 9 controls the degree of overlap of each slice image 7a on the same display screen. , 7b, and 7c. The state of these controls is shown in FIGS. 2 to 4. 2 shows the case where both the degree of superimposition and the viewing angle are the smallest, FIG. 4 shows the case where the degree of superimposition and the viewing angle are the largest, and FIG. 3 shows the case between the two.

Since the degree of superimposition and display viewing angle of the composite display image can be arbitrarily selected in this way, the display state of the organ to be diagnosed can be optimally controlled, and the diagnostic accuracy can be further improved.

Here, for example, if a contour line indicating the boundary between the myocardium and the intracardiac cavity is determined in advance and the contour line data is also incorporated into the composite image data at the time of image composition, the movement of the contour line in the displayed image can be observed. Since it can be observed, the wfgi viscosity of the heart can be further improved.

In addition, the electrocardiogram of the same subject can be detected and the data deleted.
It is stored in the external storage device @3 along with the data, and
As shown in the figure, if the graph pattern 10 is simultaneously displayed on the image I11 display 5 when the animation of the composite image is displayed, the diagnostic findings obtained from the electrocardiogram can be compared with the animation composite image of the actual heart. As a result, diagnostic accuracy can be improved.

[Effects of the Invention] As described above, according to the present invention, tomographic images in each slice of an organ that undergoes periodic motion, such as the heart, are synchronously displayed for one cycle on the same screen of an image display. Since the animation is displayed, it is possible to understand the movement of the organ as a whole by observing this composite display image, and therefore it is easy to understand the degree of expansion of the diseased area and the state of stimulus conduction. Disease diagnostic viscosity and diagnostic efficiency can be improved.
