Radiation imaging system, communication method of radiation imaging system, and radiographic image detecting device

A communication method of a radiation imaging system including a radiation source for emitting radiation to an object;

• a source control device for controlling an operation of said radiation source;
• a radiographic image detecting device for detecting a radiographic image by measuring said radiation passed through said object, said radiographic image detecting device having an AEC sensor for performing automatic exposure control that stops a radiation emission from said radiation source based on a radiation dose passed through said object;
• and a console for receiving said radiographic image from said radiographic image detecting device, said communication method comprising:
• a high speed communication step for communicating at a relatively high communication speed an AEC signal related to said automatic exposure control between said source control device and said radiographic image detecting device;
• and
• a low speed communication step for wirelessly communicating a signal other than said AEC signal between said radiographic image detecting device and said console at a communication speed lower than said communication speed of said AEC signal.

A radiographic image detecting device to be used in combination with a radiation source for emitting radiation to an object and a source control device for controlling an operation of said radiation source, for detecting a radiographic image by measuring said radiation passed through said object, said radiographic image detecting device comprising:
