An apparatus for controlling tomosynthesis imaging according to the present invention enables outputting only an oblique image as a diagnosis target, and alleviating the load on communication as well as the capacity load on a PACS server. When a reconstructed. tomosynthesis image is transmitted to an external apparatus such as the PACS server, transmitting only the required tomographic image(s) instead of transmitting the entire frame data enables efficient use of the storage capacity. Further, transmitting an oblique image with appended parameters enables efficient performance of diagnosis on an image from an external apparatus of a transmission destination, without performing reconstruction, thus facilitating re-imaging under an identical condition for the purpose of progress observation.
