RADIATION IMAGING APPARATUS, MANUFACTURING METHOD OF THE SAME, AND RADIATION IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technique advantageous to obtain high quality radiation image.SOLUTION: A radiation imaging apparatus comprises: a sensor panel including a sensor array in which a plurality of sensors for photoelectric conversion are arranged in an array shape and a scintillator layer arranged on the sensor array; and a unit for performing signal processing based on a signal from the sensor array outputted by the sensor panel. The sensor array has a peripheral region and a central region arranged inside the peripheral region. The scintillator is arranged covering the peripheral region and the central region so as to have uniform luminous efficiency to the sensor array. The scintillator layer is arranged across the peripheral region and the central region so as to have uniform luminous efficiency to the sensor array. The unit performs signal processing by using only the signal from each of the sensors arranged in the central region among the signals from the plurality of sensors outputted by the sensor panel.
