Abstract

According to one embodiment, a medical image diagnostic apparatus includes a gantry and a screen. The gantry for medical imaging includes a bore. The screen is insertable into the bore. A predetermined image is projected by a projector on the screen. The screen forms a shape that enables light generated by the projector to arrive at an inner wall of the gantry.

First claim

The invention claimed is:

1. A medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore; and
a screen which is insertable into the bore and on which a predetermined image is projected by a projector, wherein
the screen is configured to form a shape that enables light generated by the projector to arrive at an inner wall of the gantry,
a projected image projected by the projector includes a first region projected on the screen and a second region projected on the inner wall, and
the first region and the second region have different image content.

2. A medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore; and
a screen which is insertable into the bore and on which a predetermined image is projected by a projector, wherein
the screen is configured to form a shape that enables light generated by projector to arrive at an inner wall of the gantry,
a projected image projected by the projector includes a first region projected on the screen and a second region projected on the inner wall, and
at least one among a hue, brightness, and a pattern is different between an image in the first region and an image in the second region.

3. The medical image diagnostic apparatus according to claim 2 , wherein an image in the second region is obtained by changing at least one among the hue, the brightness, and the pattern depending on a position of the inner wall along a circumferential direction.

4. A Theft medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore; and
a screen which is insertable into the bore and on which a predetermined image is projected by a projector, wherein
the screen is configured to form a shape that enables light generated by the projector to arrive at an inner wall of the gantry,
a projected image projected by the projector includes a first region projected on the screen and a second region projected on the inner wall, and
an image in the second region corresponds to an image obtained by trimming the projected image in accordance with the screen.

5. The medical image diagnostic apparatus according to claim 4 , wherein an image in the second region is an image obtained by changing at least one of brightness and a hue from a position corresponding to a boundary of the trimming in the projected image toward an outer edge of the second region.

6. The medical image diagnostic apparatus according to claim 4 , wherein an image in the second region has a brightness that at a position corresponding to a boundary of the trimming in the projected image is equal to a brightness of an outer edge portion of the first region and the brightness of the second region decreases from the position corresponding to the boundary of the trimming toward an outer edge of the second region.

7. A medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore;
a screen which is insertable into the bore and on which a predetermined image is projected by a projector, and
control circuitry which controls an irradiation range of irradiation light on an inner wall depending on a position of the screen, wherein
the screen is configured to form a shape that enables light generated by the projector to arrive at the inner wall of the gantry,
a projected image projected by the projector includes a first region projected on the screen and a second region projected on the inner wall, and
the gantry includes a plurality of irradiators arrayed along the central axis on a space between a side face of a couch top which is movable along a central axis of the bore together with the screen, and the inner wall, or arrayed along the central axis on the inner wall positioned lower than an upper face of a headrest provided on the couch top, the irradiators irradiating the inner wall with the irradiation light having a hue corresponding to an image in the second region.

8. A medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore; and
a screen which is insertable into the bore and on which a predetermined image is projected by a projector, wherein
the screen is configured to form a shape that enables light generated by the projector to arrive at an inner wall of the gantry, and
a surface of the inner wall has a diffuse reflection function of diffusing and reflecting light projected by the projector in order to improve projection efficiency of an image projected on the inner wall.

9. A medical image diagnostic apparatus comprising:
a gantry for medical imaging which includes a bore;
a screen which is insertable into the bore and on which a predetermined image is projected by a projector; and
a movable carriage which includes at least one irradiator configured to emit irradiation light having a hue corresponding to an image in a second region toward a position of an inner wall of the gantry on which the image corresponding to the second region is projected, and which is configured to movably support the screen along a central axis of the bore, wherein
the screen is configured to form a shape that enables light generated by the projector to arrive at the inner wall of the gantry, and
a projected image projected by the projector includes a first region projected on the screen and the second region projected on the inner wall.

10. The medical image diagnostic apparatus according to claim 9 , wherein the irradiator is installed at a position which prevents the irradiation light from arriving at a reflecting plate configured to reflect a part of the projected image projected on the screen, and at the screen.

11. The medical image diagnostic apparatus according to claim 9 , wherein the movable carriage further including a shielding plate configured to shield irradiation of the irradiation light with respect to a reflecting plate configured to reflect a part of the projected image projected on the screen, and with respect to the screen.
