Abstract
A radiation source distribution image of an examinee is formed by driving X direction movement motors to move a radiation information-detecting unit in the X direction, and detecting radiation from the examinee on a stretcher placed between guide rails by using a collimator and a line sensor which constitute a detection unit.
Claims11
An apparatus for forming a radiation source distribution image for detecting radiation radiated from a radiation source in an examinee to form a distribution image of said radiation source in said examinee, said apparatus comprising:
- a line sensor including a plurality of radiation-detecting elements for detecting said radiation, said plurality of radiation-detecting elements being arranged one-dimensionally;
- a coded aperture plate arranged between said line sensor and said examinee, including a plurality of apertures arranged according to a predetermined array rule in a direction of said radiation-detecting elements;
- a movable means for moving said line sensor and said coded aperture plate in a direction perpendicular to said direction of said radiation-detecting elements;
- an image-forming means for forming said distribution image of said radiation source based on said radiation detected by said radiation-detecting elements;
- and
- a display means for displaying said distribution image of said radiation source formed by said image-forming means.
