Radiation imaging system, imaging stand, and imaging method

A radiation imaging system comprising:

• a radiation detector group which includes a plurality of radiation detectors configured to have an imaging surface, on which radiation is incident, and to generate a radiation image of an imaging target according to radiation transmitted through the imaging target and incident on the imaging surface, adjacent radiation detectors being arranged in parallel in a direction intersecting an incidence direction of radiation and the end portions of the imaging surfaces of adjacent radiation detectors overlapping each other in the incidence direction of radiation;
• a grid which has an effective area narrower than the imaging surface by the radiation detector group and eliminates scattered radiation included in radiation transmitted through the imaging target and incident on the effective area;
• and
• a holding unit which is able to hold the grid at a plurality of positions along the imaging surface where a first area where the end portions of adjacent radiation detectors overlap each other and the end portion of the grid are separated in the intersection direction, and the imaging surface and the effective area overlap each other.
