Abstract

A medical image diagnosis system according to one embodiment includes a gantry, a couch, a reflecting plate, and a processing circuitry. The gantry is for medical imaging having a bore. The couch movably supports a top plate. The reflecting plate reflects an image output from an image output device. The processing circuitry, in a first case where the image is shown to an observer not through the reflecting plate, outputs a first image signal relating to a first image to the image output device. While in a second case where the image is shown to the observer through the reflecting plate, The processing circuitry outputs a second image signal relating to a second image to the image output device.

First claim

The invention claimed is:

1. A medical image diagnosis system, comprising:
a gantry for medical imaging, the gantry having a bore;
a top plate;
a couch configured to movably support the top plate;
a display unit disposed in the bore of the gantry and configured to display an output image;
a reflecting plate configured to reflect the output image output from the display unit, the reflecting plate being provided in front of the display unit;
a detector configured to detect a position of the reflecting plate, the position being associated with a rotation angle of the reflecting plate and/or a presence of the reflecting plate; and
processing circuitry configured to:
determine, based on the detected position of the reflecting plate, whether switching between a first projection mode and a second projection mode is required, the first projection mode allowing the output image displayed on the display unit to be viewed by an observer from an outside of the bore of the gantry not through the reflecting plate, and the second projection mode allowing the output image displayed on the display unit to be viewed by an observer placed on the top plate through the reflecting plate, wherein the processing circuitry determines that the first projection mode is required in a case where the detected position of the reflecting plate indicates a first rotation angle, and the processing circuitry determines that the second projection mode is required in a case where the detected position of the reflecting plate indicates a second rotation angle, the first and second rotation angles being angles formed by the reflecting plate and a direction along the bore of the gantry, the first rotation angle being smaller than the second rotation angle, and
switch the output image between a first output image and a second output image that is an inverted image of the first output image based on the determination that switching between the first projection mode and the second projection mode is required, the first output image being displayed on the display unit to be viewed not through the reflecting plate in the first projection mode, and the second output image being displayed on the display unit in place of the first output image to be viewed through the reflecting plate in the second projection mode.

2. The medical image diagnosis system according to claim 1 , wherein
the processing circuitry is further configured to switch the output image between playing a first video including a plurality of first output images and playing a second video including a plurality of second output images that represent contents identical to contents of the plurality of first output images, and to replay a corresponding portion of the contents of the first video or the second video at switching.

3. The medical image diagnosis system according to claim 1 , wherein
the first output image is to be displayed on the display unit when the observer is outside the bore, and the second output image is to be displayed on the display unit when the observer is placed on the top plate.

4. The medical image diagnosis system according to claim 1 , wherein the display unit includes a screen disposed in the bore of the gantry and configured to display the first and second output images which are provided by an image output device.

5. A medical image diagnosis system, comprising:
a gantry for medical imaging, the gantry having a bore;
a top plate;
a couch configured to movably support the top plate;
an image output device configured to output an output image;
a screen disposed in the bore of the gantry and configured to display the output image provided by the image output device;
a reflecting plate configured to reflect the output image displayed on the screen, the reflecting plate being provided in front of the screen;
a detector configured to detect a position of the reflecting plate, the position being associated with a rotation angle of the reflecting plate and/or a presence of the reflecting plate; and
processing circuitry configured to
determine, based on the detected position of the reflecting plate, whether switching between a first projection mode and a second projection mode is required, the first projection mode allowing the output image displayed on the screen to be viewed by an observer from an outside of the bore of the gantry not through the reflecting plate, and the second projection mode allowing the output image displayed on the screen to be viewed by an observer placed on the top plate through the reflecting plate, wherein the processing circuitry determines that the first projection mode is required in a case where the detected position of the reflecting plate indicates a first rotation angle, and the processing circuitry determines that the second projection mode is required in a case where the detected position of the reflecting plate indicates a second rotation angle, the first and second rotation angles being angles formed by the reflecting plate and a direction along the bore of the gantry, the first rotation angle being smaller than the second rotation angle, and
control the image output device to switch the output image between a first output image and a second output image that is an inverted image of the first output image based on the determination that switching between the first projection mode and the second projection mode is required, the first output image being displayed on the screen to be viewed not through the reflecting plate in the first projection mode, and the second output image being displayed on the screen in place of the first output image to be viewed through the reflecting plate in the second projection mode.

6. The medical image diagnosis system according to claim 5 , wherein
the processing circuitry is further configured to switch the output image between playing a first video including a plurality of first output images and playing a second video including a plurality of second output images that represent contents identical to contents of the plurality of first output images, and to replay a corresponding portion of the contents of the first video or the second video at switching.

7. The medical image diagnosis system according to claim 5 , wherein
the first output image is to be displayed on the screen when the observer is outside the bore, and the second output image is to be displayed on the screen when the observer is placed on the top plate.
