This graphic screen is, for example, G shown in FIG.
D is a data display pattern portion, and B is a body pattern portion.

The video data generation unit 8 combines the image screen and the graphic screen, and outputs a video signal of the combined screen to the display 9.

Therefore, an image is displayed on the display 9 as shown in S in FIG.

Next, when the operator selects the multi mode and designates a plurality of images to be displayed, the master controller 3 issues a multi-mode display instruction and an image extraction instruction to the image control unit 5 with the compression function and the graphic control unit 57. give.

The image control unit with a compression function 5 extracts a plurality of tomographic images from the ultrasonic imaging apparatus 4 based on the command, performs a compression process to reduce the display size, and arranges the tomographic images at a predetermined position.
The signal of the image screen is output to the video data generator 8. This image screen is, for example, I shown in FIG. 8, and t is each reduced tomographic image portion.

The graphics control unit 57 performs steps R1, R4,
As shown in R6 and R7, various data display patterns and body patterns are extracted from the graphic pattern memory 6 based on the command, arranged at predetermined positions on the screen, and repeated for a plurality of tomographic images to be displayed. The signal of the graphic screen is output to the video data generator 8. This graphic screen is, for example, G shown in FIG. 8, D is a data display pattern portion, and B is a body pattern portion.

The video data generation unit 8 combines the image screen and the graphic screen, and outputs a video signal of the combined screen to the display 9.

Therefore, an image such as M shown in FIG. 8 is displayed on the display 9.

[Problems to be Solved by the Invention] In the ultrasonic diagnostic apparatus 51, since the tomographic image t is reduced in the multi-mode, the tomographic image t is necessarily harder to read than in the single mode.

However, not only that, as can be seen by comparing the image display in the single mode (S in FIG. 7) and the image display in the multi mode (M in FIG. 8), the image in the single mode can be seen. In the display (S in FIG. 7), while the overlap between the tomographic image T and the body pattern B is small,
In the image display in the multi-mode (M in FIG. 8), the overlap between the tomographic image t and the body pattern B is increased. Due to this reason, it is difficult to read the tomographic image t in the multi-mode as compared with the single mode. ing.

That is, in the conventional tomographic image display apparatus, there is a problem that the display in the multi mode is extremely difficult to see as compared with the display in the single mode.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tomographic image display device in which the visibility of a display in a multi-mode is improved.

[Means for Solving the Problems] The tomographic image display device of the present invention displays, on the same screen, a tomographic image of a human body obtained by a tomographic image capturing device and a body pattern indicating a part of the human body from which the tomographic image is obtained. In a tomographic image display device for displaying an image, a mode selecting means for performing switching selection between at least two modes of a single mode and a multi mode, and when a single mode is selected, one tomographic image and a corresponding body pattern are displayed. Single mode display means for displaying an image, and when the multi mode is selected, the display size of the tomographic image is reduced from that in the single mode to display a plurality of tomographic images on the same screen, and each of the displayed plurality of tomographic images is displayed. Multi-mode display means for reducing the body pattern corresponding to that in the single mode and displaying an image in an arrangement close to each tomographic image This is a feature of the configuration.

In the above configuration, the reduction of the body pattern may be performed by compression every time the display is performed. Alternatively, the reduced body pattern may be stored separately from the non-reduced body pattern and extracted each time the display is performed. .

[Operation] In the tomographic image display device of the present invention, not only the tomographic image is reduced in the multi mode, but also the body pattern is reduced.

The tomographic image and the body pattern should be displayed at close positions to clarify the correspondence, but since the body pattern is also reduced as described above, even if they are placed close, they will overlap. And the visibility is improved as compared with the conventional case.

[Example] Hereinafter, the present invention will be described in more detail with reference to an example shown in the drawings. It should be noted that the present invention is not limited by this.

FIG. 1 is a block diagram of an ultrasonic diagnostic apparatus 1 which is an embodiment of a tomographic image display apparatus according to the present invention.

In this ultrasonic diagnostic apparatus 1, a keyboard 2, a master controller 3, an ultrasonic imaging apparatus 4, an image control unit 5 with a compression function, a graphic pattern memory 6, a video data generating unit 8, and a display 9 are arranged as shown in FIG. The components are the same as those of the ultrasonic diagnostic apparatus 51.

A component different from the conventional ultrasonic diagnostic apparatus 51 of FIG. 5 is the graphic control unit 7 with a compression function. FIG. 2 shows a flowchart of the main operation.

When the operator selects the single mode via the keyboard 2 and designates one image to be displayed, the master controller 3 displays the single mode display on the image controller 5 with the compression function and the graphic controller 7 with the compression function. And an instruction to extract an image.

The image control unit 5 with a compression function extracts only one tomographic image from the ultrasonic imaging apparatus 4 based on the command, and outputs a signal of the image screen to the video data generation unit 8 without performing compression processing. .

The graphics controller with compression function 7 extracts various data display patterns and body patterns from the graphic pattern memory 6 based on the command and arranges them at predetermined positions on the screen, as shown in steps S1 to S3 in FIG. And
The signal of the graphic screen is output to the video data generator 8.

The video data generation unit 8 combines the image screen and the graphic screen, and outputs a video signal of the combined screen to the display 9.

Therefore, an image is displayed on the display 9 as shown in S in FIG. T is a tomographic image, D is a data display pattern, and B is a body pattern.

The operation in the single mode is the same as the conventional operation, and the image display S in FIG. 3 is the same as S shown in FIG.

Next, when the operator selects the multi mode and designates a plurality of images to be displayed, the master controller 3 instructs the image control unit 5 with the compression function and the graphic control unit 7 with the compression function to issue a multi-mode display command and an image. Command to take out.

The image control unit with a compression function 5 extracts a plurality of tomographic images from the ultrasonic imaging apparatus 4 based on the command, performs a compression process to reduce the display size, and arranges the tomographic images at a predetermined position.
The signal of the image screen is output to the video data generator 8. This image screen is, for example, I shown in FIG. 4, and t is each reduced tomographic image portion.

The graphics control unit 7 with the compression function extracts various data display patterns and body patterns from the graphic pattern memory 6 based on the command, as shown in steps S1 and S4 to S7 in FIG. Then, the image is arranged at a predetermined position on the screen, and this is repeated for a plurality of tomographic images to be displayed. This graphic screen is, for example, g shown in FIG. 4, D is a data display pattern portion, and b is a body pattern portion.
The display size of the body pattern b is smaller than that of the body pattern B in the single mode.

The video data generation unit 8 combines the image screen and the graphic screen, and outputs a video signal of the combined screen to the display 9.

Thus, an image such as m shown in FIG. 4 is displayed on the display 9.

As can be understood by comparing the image display m (FIG. 4) according to the present invention with the conventional image display M (FIG. 8), the overlap between the tomographic image and the body pattern is smaller in the present invention than in the related art. Therefore, the conventional problem that the visibility is improved and the image display in the multi mode is extremely difficult to see than in the single mode is improved.

[Effect of the Invention] According to the tomographic image display device of the present invention, it is easy to view images in the single mode in which one tomographic image is displayed on the screen and in the multi-mode in which a plurality of tomographic images are reduced and displayed on the same screen.
