Abstract
A radiation imaging apparatus comprises a radiation generator configured to irradiate an object with radiation, a radiation detector configured to detect radiation transmitted through the object, a detector configured to detect movement or rotation or both of the radiation generator and the radiation detector relative to the object, and a controller configured to change the size of the irradiated region of the object based on a detection result.
Claims9
A radiation imaging apparatus comprising:
- a radiation generator arranged to irradiate an object with radiation;
- a radiation detector arranged to detect radiation transmitted through the object;
- a detector arranged to detect at least one of movement and rotation of said radiation generator and said radiation detector;
- and
- a controller arranged to control said radiation generator to reduce a size of an irradiated region of the object on a side of a region opposite to a direction of movement of the irradiated region in accordance with at least one of the detected movement and the detected rotation.
A processing method in a radiation imaging apparatus which obtains a radiographic image, the method comprising:
- causing a radiation generator to irradiate an object with radiation;
- causing a radiation detector to detect radiation transmitted through the object;
- detecting at least one of movement and rotation of the radiation generator and the radiation detector;
- and
- controlling the radiation generator to reduce a size of an irradiated region of the object on a side of a region opposite to a direction of movement of the irradiated region in accordance with at least one of the detected movement and the detected rotation.
A radiation generator control apparatus comprising:
- a detector arranged to detect at least one of movement and rotation of a radiation generator arranged to irradiate an object with radiation and a radiation detector arranged to detect radiation transmitted through the object;
- and
- a controller arranged to control the radiation generator to reduce a size of an irradiated region of the object on a side of a region opposite to a direction of movement of the irradiated region in accordance with at least one of the detected movement and the detected rotation.
