Patent ID: 8903048

Claim:
A radiographic imaging apparatus for use with a radiation generating apparatus for emitting radiation, comprising: an image detector, having an imaging area in which plural pixels are arranged in arrays for storing a signal charge according to a radiation dose of said radiation upon receiving said radiation from said radiation generating apparatus, for detecting a radiation image by receiving radiation transmitted through an object; a radiation detector for outputting a detection signal according to said radiation dose, in order to detect an emission start of said radiation from said radiation generating apparatus, and/or in order to measure a total radiation dose of said radiation; a communication interface for communicating with said radiation generating apparatus; a mode selector for selectively setting one of first and second operating modes; wherein said first operating mode is used in case of combination with said radiation generating apparatus with which said communication interface has communication compatibility, for performing at least an exposure control for measuring said total radiation dose according to said detection signal from said radiation detector; said second operating mode is used in case of combination with said radiation generating apparatus with which said communication interface has communication incompatibility, for performing at least a control of start synchronization for detecting said emission start according to said detection signal from said radiation detector and starting a storage step of storing said signal charge of said image detector in synchronism with said emission start; a controller for controlling said image detector according to said one operating mode selectively set by said mode selector.
