Abstract
Provided are a portable radiographic image detector capable of transmitting with a smaller number of transmissions the read results of dark reads performed a plurality of times when an offset calibration or the like is carried out, and a radiographic image generation system using the portable radiographic image detector. The portable radiographic image detector comprises: a sensor panel with a plurality of radiation detector elements; a storage means for storing dark read values outputted from the radiation detector elements; a calculation means for calculating the offset correction value for each of the radiation detector elements, based on a plurality of dark read values obtained from the outputs of the radiation detector elements at every dark read of a plurality of times of dark reads previously performed; a communication means for transmitting the offset correction value for each of the radiation detector elements to an external device; and a built-in battery.
