Claim Text:
1. A radiation imaging apparatus comprising: an irradiation unit configured to irradiate a subject with radiations; a control unit configured to continuously adjust energy of the radiations in one shot emitted by the irradiation unit; a generation unit configured to generate a plurality of image data pieces in one shot by detecting the radiations whose energy is continuously adjusted by the control unit and transmitted through the subject; a classification unit configured to classify the plurality of image data pieces generated by the generation unit into image data generated by the radiations of a high energy side and image data generated by the radiations of a low energy side; a subtraction unit configured to perform weighting and subtraction on the image data generated by the radiations of the high energy side and the image data generated by the radiations of the low energy side; and a changing unit configured to change a frame rate of the image data generated by the generation unit, wherein the changing unit changes the frame rate based on at least one of an imaging region of the subject and an age of the subject.
