Abstract
In a radiographic image detection apparatus that can perform long-size radiography on a region of a patient that is larger than the detection range of a radiographic image detector, radiography is performed so that a collimator image is included in a radiographic image in such a manner that the collimator image is present in the vicinity of a side edge of the radiographic image. Further, the inclination of each radiographic image caused by inclination of the radiographic image detector at the time of radiography is corrected based on the collimator image. Further, a synthesis image is produced by combining the plurality of radiographic images the inclination of which has been corrected.
Claims5
A radiographic image detection apparatus comprising:
- a radiation source including a collimator that determines the irradiation range of radiation that is output to a subject;
- a radiographic image detector that detects, as a radiographic image, the radiation that has been output from the radiation source and transmitted through the subject;
- a detector movement means that moves the radiographic image detector parallel to a radiation detection surface;
- an imaging control means that controls the collimator of the radiation source so that a collimator image that extends along the movement direction of the radiographic image detector is included in the radiographic image;
- an image correction means that corrects the inclination of the radiographic image based on the collimator image in the radiographic image detected by the radiographic image detector;
- and
- an image synthesis means that produces a synthesis image by combining a plurality of radiographic images corrected by the image correction means.
