X-RAY CT APPARATUS, DISPLAY METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
According to one embodiment, an X-ray CT apparatus includes a scanner, a stand, and a processing circuit. The scanner has an opening into which a subject is inserted. The stand supports the scanner so as to enable the scanner to move in a vertical direction. The processing circuit acquires an inner image captured by imaging an inside of the opening from a camera. The processing circuit generates a visualized image by visualizing the inside of the opening viewed from a visual line direction toward the inside of the opening based on the inner image. The processing circuit causes a display unit to display the visualized image.
1 . An X-ray CT apparatus comprising:
a scanner having an opening into which a subject is inserted;
a stand configured to support the scanner so as to enable the scanner to move in a vertical direction; and
a processing circuit configured to acquire an inner image captured by imaging an inside of the opening from a camera,
generate a visualized image by visualizing the inside of the opening viewed from a visual line direction toward the inside of the opening based on the inner image, and cause a display unit to display the visualized image.
2 . The apparatus according to claim 1 , wherein the visualized image displays actual laser light that is actually projected from a projector onto the subject and indicates a height of an imaging section in the subject.
3 . The apparatus according to claim 1 , wherein the visualized image displays virtual laser light that is planned to be projected onto the subject and indicates a height of an imaging section in the subject.
4 . The apparatus according to claim 3 , wherein the visualized image does not display the virtual laser light while laser light is actually projected from the projector onto the subject.
5 . The apparatus according to claim 3 , wherein the processing circuit moves a position of the virtual laser light on the visualized image in accordance with an operation from a user and moves the scanner in accordance with the position of the virtual laser light after the movement.
6 . The apparatus according to claim 1 , wherein the display unit is provided on a surface of at least one of the scanner and the stand, and
the processing circuit acquires an opposite side image captured by imaging a space on an opposite side to the surface provided with the display unit from another camera and causes the display unit to display the opposite side image.
7 . The apparatus according to claim 1 , further comprising:
a rail provided on a surface of at least one of the scanner and the stand; and
a moving mechanism configured to move the display unit along the rail.
8 . The apparatus according to claim 7 , wherein the visual line direction is a direction extending from a position where the display unit is provided to a central position of the opening, and
the moving mechanism moves the display unit so as to locate a user on a straight line indicating the visual line direction.
9 . The apparatus according to claim 1 , wherein the visualized image schematically displays the subject as a schema.
10 . The apparatus according to claim 1 , wherein the display unit is a portable terminal carried by a user.
11 . The apparatus according to claim 1 , wherein the display unit is provided on a surface of at least one of the scanner and the stand, and the apparatus further comprises a projector configured to project the visualized image onto the surface provided with the display unit.
12 . The apparatus according to claim 1 , wherein the display unit is a display, and
the processing circuit selectively turns on and off a power source of the display in accordance with at least one of a posture of the scanner and an imaging mode of the scanner.
13 . The apparatus according to claim 1 , wherein the display unit is provided on a surface of the stand which is located on an opposite side to a surface that the scanner and the stand face, and
the processing circuit generates a visualized image viewed from a visual line direction extending from a position where the display unit is provided to the central position of the opening.
14 . A display method for an X-ray CT apparatus including a scanner having an opening into which a subject is inserted and a stand configured to support the scanner so as to enable the scanner to move in a vertical direction, the method comprising causing a computer to
acquire an inner image captured by imaging an inside of the opening from a camera;
generate a visualized image by visualizing the inside of the opening viewed from a visual line direction toward the inside of the opening based on the inner image; and
cause a display unit to display the visualized image.
15 . A non-transitory computer readable medium for an X-ray CT apparatus including a scanner having an opening into which a subject is inserted and a stand configured to support the scanner so as to enable the scanner to move in a vertical direction, the medium including computer executable instructions, wherein the instructions, when executed by a processing circuit, cause the processing circuit to perform a method comprising:
acquiring an inner image captured by imaging an inside of the opening from a camera;
generating a visualized image by visualizing the inside of the opening viewed from a visual line direction toward the inside of the opening based on the inner image; and
causing a display unit to display the visualized image.
