Abstract:
1. A radiation imaging apparatus comprising: a sensor panel including a sensor array on which a plurality of sensors which perform photoelectric conversion are arranged in an array form and a scintillator layer provided on the sensor array; and a unit configured to generate a radiation image based on a signal from the sensor array which is output from the sensor panel and output the generated radiation image, wherein the sensor array includes a peripheral region and a central region located inside the peripheral region, wherein the plurality of sensors includes sensors disposed in the central region of the sensor array and sensors disposed in the peripheral region of the sensor array, wherein the scintillator layer is disposed over the peripheral region and the central region by direct vapor deposition or direct coating so as to have uniform luminance efficiency with respect to the sensor array, and wherein the unit generates the radiation image by using only signals from sensors disposed in the central region of the sensor array.
