<p>An X-ray imaging apparatus comprising an annular holder whose radial direction is perpendicular to the floor, an annular rotary body held rotatably along the inner peripheral surface of the holder, X-ray sources disposed in radially opposed positions on the inner peripheral surface of the rotary body, and flat-panel two-dimensional X-ray sensor, wherein the rotary body is rotated to acquire X-ray image data collected omnidirectionally from a subject positioned in the space in the rotary body. The X-ray imaging apparatus is excellent in space factor of when the X-ray tube or the two-dimensionally X-ray sensor rotates.</p> |
