  • Patent number: 10349913
    Abstract: A derivation unit derives imaging conditions corresponding to virtual grid characteristics (grid ratio) received by a receiving unit on the basis of a table stored in a storage unit. The derivation unit sets the derived imaging conditions in a radiation source control unit. The radiation source control unit controls a radiation source on the basis of the set imaging conditions such that a radiographic image is captured. An execution unit of an image processing device acquires the radiographic image captured by the radiation detector through a detector control unit. The execution unit performs a virtual grid process for the acquired radiographic image on the basis of the virtual grid characteristics received by the receiving unit and the imaging conditions derived by the derivation unit to generate a radiographic image from which the influence of scattered radiation has been removed and displays the radiographic image on a display unit.
