<p><P>PROBLEM TO BE SOLVED: To provide a three-dimensional image at a high speed without rotating an arm or using a large-scaled apparatus by using an X-ray generator and a plane detector facing each other by the arm. <P>SOLUTION: A multiple X-ray generator 22 for emitting X-rays from M×N pieces of two-dimensionally arrayed X-ray sources is fixed to one end of a C arm 21 attached to a base part, and the plane detector 24 provided with K×L pieces of sensors for detecting an X-ray dose is provided on the other end of the C arm 21. Between the multiple X-ray generator 22 and the plane detector 24, a top plate for mounting a subject is disposed. By switching the X-ray source by a manual or automatic operation, the X-ray source of the multiple X-ray generator 22 is switched and imaging from many X-ray source directions as indicated in (a) and (b) is made possible. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
