<P>PROBLEM TO BE SOLVED: To provide an imaging aid and a radiation imaging method for preventing a marker from being missed and reliably arranging the marker between a subject and a radiation detector with a predetermined gap, in tomosynthesis imaging. <P>SOLUTION: The imaging aid includes a plurality of markers formed in predetermined positions on its surface, the markers being captured together with the subject and used for aligning a plurality of radiation images. By irradiating the subject positioned on an imaging platform using the imaging aid at different irradiation angles while moving a radiation source in one direction, a plurality of radiation images of different imaging angles are captured in order by tomosynthesis imaging. Image synthesis processing is performed by superimposing the aligned radiation images on the basis of positions of markers captured in the plurality of radiation images to reconfigure radiation tomographic images in a predetermined cross-section of the subject. <P>COPYRIGHT: (C)2012,JPO&INPIT |
