<p>The invention provides a radiation imaging apparatus with superior operability. That is, the invention is configured so that imaging is possible even if the operator does not adjust the degree of opening of the collimator (3a). A collimator control unit (18b) controls the collimator drive mechanism (18a) so that radiation is irradiated only on the input area of the FPD (4) on the basis of the input area and imaging distance information stored in association with the imaging mode. As a result, the subject (M) is not exposed to unnecessary radiation even if the operator does not adjust the degree of opening of the collimator (3a). The invention provides a radiation imaging apparatus with superior operability in which manual adjustment of the degree of opening of the collimator (3a) has been eliminated.</p> |
