PROBLEM TO BE SOLVED: To restrict display of an image inappropriate for diagnosis and reduce a burden on an operator.SOLUTION: A control device of tomosynthesis imaging for obtaining a tomosynthesis image from a projection image group imaged by irradiating a subject with X-rays from a plurality of different angles by using an X-ray generation unit and an X-ray detection unit includes: a communication circuit which transmits a drive condition to the X-ray detection unit, receives the plurality of projection images from the X-ray detection unit, and receives the position information of the X-ray generation unit and the X-ray detection unit at the time of obtaining the projection images from an external device determination means which determines an invalid image region on the basis of the position information and display control means which makes a display unit display the tomosynthesis image obtained in accordance with the determination result.
