<p><P>PROBLEM TO BE SOLVED: To solve problems by removing scattered rays caused by relative movement of a radiation detector and a grid in a simple constitution in equipment radiographing a subject by integrally rotating an imaging system comprising an X-ray tube and a radiation detector disposed oppositely to each other. <P>SOLUTION: This radiographic equipment is provided with the imaging system consisting of the X-ray tube applying radiation to the subject and the two-dimensional radiation detector detecting the radiation transmitting through the subject, which are oppositely disposed in the both sides of the subject, applies the radiation to the subject while integrally rotating the imaging system and detects the radiation projected image of the subject by the radiation detector. This radiographic equipment is disposed with a grid into a tubular shape surrounding the body axis of the subject, the X-ray tube in a space sandwiched in between the subject and the grid, and the radiation detector in an outside space of the grid disposed in the tubular shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
