Abstract
A radiation imaging system stabilizes a change in temperature of a radiation imaging apparatus, obtains a radiation image of an object based on radiation applied from a radiation source and reaching through the object, obtains a correction image by performing imaging without irradiation with the radiation from the radiation source, performs, using the correction image, image processing for correcting an offset component appearing in the radiation image on the radiation image, and determines whether stabilization of a change in temperature of the radiation imaging apparatus is effectively functioning. The radiation imaging system switches modes of obtaining the correction image based on determination.
