Abstract
A radiographic imaging apparatus includes a radiation detection circuit with elements arranged two-dimensionally to convert radiation into an electrical signal, a driving mechanism which changes a positional relationship between the components, a memory which stores that electrical signal, an imaging controller to control the radiation source so as to emit a first radiation pulse at a first energy for a first frame and to emit a second radiation pulse at a second energy for a second frame, controlling the driving mechanism to maintain the positional relationship during the first radiation pulse and the second radiation pulse and to change the positional relationship in a period between the first period and the second period. The frames are different and sequentially imaged, and an image processing unit for subtraction processing of the first and second frames in memory to generate a processed image, then generate a tomographic and a 3D image.
