PROBLEM TO BE SOLVED: To provide a radiation imaging apparatus advantageous for correcting a signal from a sensor for cancelling a noise component.SOLUTION: The radiation imaging apparatus includes: a plurality of sensors which are arrayed so as to form a plurality of rows and a plurality of columns a drive section which drives the plurality of sensors for the unit of a row and a reading section for reading signals from the sensors of each column. The drive section performs a first operation for iteratively initializing the plurality of sensors before irradiation with radial rays, and a second operation for driving the plurality of sensors so as to read signals from the plurality of sensors by means of the reading section in response to the irradiation with radial rays. The first operation and the second operation are performed while changing the order of rows to be driven in the first operation and the order of rows to be driven in the second operation so as to generate a difference between the neighboring rows in the time from the final initialization of the sensor during the first operation to the read-out of the signal during the second operation.COPYRIGHT: (C)2016,JPO&INPIT【課題】センサからの信号に対してノイズ成分を除去するための補正を行うのに有利な放射線撮像装置を提供する。【解決手段】放射線撮像装置は、複数の行および複数の列を形成するように配列された複数のセンサと、前記複数のセンサを行単位で駆動する駆動部と、各列の各センサから信号を読み出す読出部と、を備える放射線撮像装置であって、前記駆動部は、放射線が照射される前には前記複数のセンサを繰り返し初期化する第1動作と、放射線が照射されたことに応答して前記読出部により前記複数のセンサから信号が読み出されるように前記複数のセンサを駆動する第2動作と、を行い、前記第1動作と前記第2動作とを、前記第1動作で駆動する行の順番と前記第2動作で駆動する行の順番とを変えて、隣接行間で、各センサが前記第1動作で最後に初期化されてから前記第2動作で信号が読み出されるまでの時間に差が生じるように行う。【選択図】図5
