<p><P>PROBLEM TO BE SOLVED: To provide a radiogram imaging device capable of acquiring a fluoroscopic image of an object to be imaged generating no halation, efficiently by reducing greatly the total work time, by dispensing with entering an inspection chamber by an inspecting worker for setting work of a shield corresponding to the shape of the object to be imaged, and by dispensing with entering the inspection chamber itself by the inspecting worker for setting work and position adjustment work of a lead clay. <P>SOLUTION: This radiogram imaging device has a constitution wherein the shield 22 is constituted of a plurality of shielding plate elements 222, 222 provided respectively independently movably, and each shield 222 is moved in a plane intersecting an irradiation optical axis of an X-ray generator or an imaging optical axis of a radiogram taking device so as to prevent at least either of direct arrival of X-rays from the X-ray generator to the radiogram taking device bypassing the object M to be imaged and halation generation in the fluoroscopic image acquired by the radiogram imaging device. <P>COPYRIGHT: (C)2004,JPO</p> |
