Abstract
An image obtaining unit obtains a plurality of radiographic images, which at least partially overlap with one another, taken by carrying out a plurality of imaging operations with respect to an identical subject. An imaging information obtaining unit obtains imaging information representing imaging conditions and an imaged subject during the imaging operations. A body motion index value obtaining unit obtains a body motion index value, which indicates a body motion of the subject during imaging of the radiographic images, based on the imaging information.
Claims23
A body motion detection device comprising:
- image obtaining unit for obtaining a plurality of radiographic images taken by carrying out a plurality of imaging operations with respect to an identical subject, the radiographic images at least partially overlapping with one another;
- imaging information obtaining unit for obtaining imaging information representing imaging conditions and an imaged subject during the imaging operations;
- and
- body motion index value obtaining unit for obtaining a body motion index value based on the imaging information, the body motion index value indicating a body motion of the subject during imaging of the radiographic images.
A body motion detection device comprising:
- image obtaining unit for obtaining a plurality of radiographic images taken by carrying out a plurality of imaging operations with respect to an identical subject, the radiographic images at least partially overlapping with one another;
- and
- body motion index value obtaining unit for obtaining different types of body motion index values according to types of motion of the subject during imaging of the radiographic images.
A radiographic imaging apparatus for obtaining a plurality of radiographic images at least partially overlapping with one another by shifting a position of a radiation detector and applying radiation transmitted through a subject to the radiation detector each time the position is shifted, the apparatus comprising:
- imaging unit for shifting the position of the radiation detector along a predetermined axis of movement, and applying radiation transmitted through the subject to the radiation detector each time the position is shifted;
- radiographic image obtaining unit for obtaining a plurality of radiographic images of the subject by reading out a signal from the radiation detector each time the position is shifted and the radiation is applied;
- body motion detecting unit for detecting a body motion of the subject during imaging of the radiographic images;
- and
- information generating unit for generating retake assisting information for assisting retake of the radiographic images if the body motion is detected.
