1. A dynamic imaging system including an imager that performs dynamic imaging of a subject with a radiation generator and a radiation detector and captures multiple frame images showing a dynamic state of the subject during the dynamic imaging, the system comprising a hardware processor configured to execute processes comprising:
obtaining positional information of a region of interest of the subject within an image region of a first frame image captured during the dynamic imaging by the imager;
determining whether or not the region of interest will be within an image region of a second frame image to be captured subsequent to the first frame image during the dynamic imaging, based on the positional information of the region of interest of the subject within the image region of the first frame image captured during the dynamic imaging; and
in response to determining that the region of interest will not be within the image region of the second frame image during the dynamic imaging, adjusting at least one of an irradiation field of the radiation generator and a position of the radiation detector according to the positional information of the region of interest.
