ABSTRACT:
A digital X-ray imaging apparatus comprises an X-ray generator 6 for generating X-rays toward a subject, an X-ray imaging device 7 for detecting an image of X-rays having passed through the subject, a swivel member 4 and a horizontal movement means 8 provided with the X-ray generator 6 and the X-ray imaging device 7 opposed to each other to relatively move the X-ray generator 6 and the X-ray imaging device 7 with respect to the subject, a CPU 21 for producing a tomographic image in accordance with an imaging signal from the X-ray imaging device 7, frame memories and an image display unit 26 for displaying the tomographic image. The X-ray imaging device 7 includes a MOS image sensor having a plurality of two-dimensional light-receiving pixels. With this configuration, a tomographic image along a given tomographic plane can be produced by a signal X-ray imaging operation, and the imaging sensitivity of the digital X-ray imaging apparatus can be enhanced.
