ABSTRACT:
A mammographic system as a radiation image capturing apparatus includes a radiation source for emitting a radiation, AEC sensors for detecting the radiation emitted from the radiation source and acquiring radiation image information for exposure control, a mammary gland position identifier for selecting at least one of the AEC sensors for outputting given radiation dose information based on the radiation dose information acquired by the AEC sensors thereby to identify a mammary gland position as a region of interest of a subject, a weighting coefficient allocator for multiplying output signals from the AEC sensors before the mammary gland position is identified by the mammary gland position identifier, by respective weighting coefficients depending on the installed positions of the AEC sensors, and a radiation source controller for controlling the radiation dose applied from the radiation source to the identified mammary gland position.
