Abstract
An X-ray imaging apparatus includes a table, an imager configured to capture a plurality of X-ray images, a rotating mechanism, a moving mechanism, and an image processor. The image processor is configured to generate a long image by performing processing of varying magnifications of the plurality of X-ray images based on an amount of relative movement of the table and the imager and splicing the plurality of X-ray images when imaging is performed at a plurality of imaging positions in a state in which an optical axis of X-rays radiated from an X-ray irradiator is inclined with respect to the table.
Claims9
An X-ray imaging apparatus comprising:
- a table on which a subject is placed;
- an imager including an X-ray irradiator configured to irradiate the subject with X-rays and an X-ray detector configured to detect the X-rays radiated from the X-ray irradiator and transmitted through the subject, the imager being configured to capture a plurality of X-ray images;
- a rotating mechanism configured to rotate the imager;
- a moving mechanism configured to move so as to change a relative position of the table to the imager;
- and
- an image processor configured to generate a long image, which is longer than each of the plurality of X-ray images, by performing processing of varying magnifications of the plurality of X-ray images based on both of an amount of relative movement of the table and the imager and an inclined angle between the table and the imager, and splicing the plurality of X-ray images when imaging is performed at a plurality of imaging positions while the table and the imager are moved relative to each other in at least one of a short-side direction or a longitudinal direction of the table in a state in which the imager is rotated such that an optical axis of the X-rays radiated from the X-ray irradiator is inclined with respect to the table.
