Abstract
The X-ray imaging apparatus is provided with an image processing unit for acquiring the presence or absence of a subject holding member, and a controller. The controller is configured to acquire a movement-prohibited direction which is a direction in which the subject holding member is not provided, based on the presence or absence of the subject holding member, and perform at least one of restricting the operation of the table top moving mechanism and notifying that the direction of tilting the table top and the movement-prohibited direction coincide, when the direction of tilting the table top and the movement prohibited direction coincide.
Claims13
An X-ray imaging apparatus comprising:
- an X-ray irradiation unit configured to emit X-rays;
- an X-ray detector configured to detect X-rays emitted from the X-ray irradiation unit;
- a table top configured to place a subject thereon;
- a table top driving mechanism configured to change a tilt of the table top;
- an imaging unit configured to image the subject placed on the table top and a subject holding member provided on the table top to hold a posture of the subject;
- an image processing unit configured to acquire presence or absence of the subject holding member, based on an image of the subject and the subject holding member captured by the imaging unit;
- and
- a controller, wherein the controller is configured to
- acquire a movement-prohibited direction which is a direction in which the subject holding member is not provided, based on the presence or absence of the subject holding member acquired by the image processing unit,
- determine whether a direction of tilting the table top by the table top driving mechanism and the movement-prohibited direction coincide, and
- perform, when the direction of tilting the table top and the movement-prohibited direction coincide, at least one of restricting an operation of the table top driving mechanism and notifying that the direction of tilting the table top and the movement-prohibited direction coincide.
An X-ray imaging system comprising:
- an X-ray irradiation unit configured to emit X-rays;
- an X-ray detector configured to detect X-rays emitted from the X-ray irradiation unit;
- a table top configured to place a subject thereon;
- a table top driving mechanism configured to change a tilt of the table top;
- an imaging unit configured to image the subject placed on the table top and a subject holding member provided on the table top to hold a posture of the subject;
- an image processing unit configured to acquire presence or absence of the subject holding member, based on an image of the subject and the subject holding member captured by the imaging unit;
- and
- a controller, wherein the controller is configured to
- acquire a movement-prohibited direction which is a direction in which the subject holding member is not provided, based on the presence or absence of the subject holding member acquired by the image processing unit,
- determine whether a direction of tilting the table top by the table top driving mechanism and the movement-prohibited direction coincide, and
- perform, when the direction of tilting the table top and the movement-prohibited direction coincide, at least one of restricting an operation of the table top driving mechanism and notifying that the direction of tilting the table top and the movement-prohibited direction coincide.
