摘要：
A radiation imaging apparatus is provided. The apparatus comprises a detection unit configured to generate an image signal according to radiation emitted by a radiation source, an image processing unit, and a control unit. The control unit performs first imaging and second imaging performed after the first imaging using radiations of different energies, the image processing unit generates an energy subtraction image using a first image signal generated by the detection unit in the first imaging and a second image signal generated by the detection unit in the second imaging, and the second imaging is performed under a radiation irradiation condition according to a noise amount included in the first image signal.
