Abstract:
1. A radiation control device comprising: a calculating unit that calculates a cumulative exposure dose from a point in time when medical treatment starts, using radiation irradiated from a radiation source to a subject to capture a movie of a radiation image, to a point in time when capturing of the movie is completed or a cumulative exposure dose received by the subject until a point in time when capturing of the movie is completed; a restricting unit that restricts an exposure dose with respect to an irradiation field of the radiation irradiated from the radiation source excluding a region of interest; a determining unit that determines whether the cumulative exposure dose calculated by the calculating unit reaches a predetermined exposure dose; and a control unit that controls the restricting unit to restrict the exposure dose, in a case in which the determining unit determines that the cumulative exposure dose reaches the predetermined exposure dose.
