摘要:
An X-ray fluoroscopic imaging apparatus capable of taking the fluoroscopic images of an arbitrary portion of an object to be examined from all directions without moving the object to be examined itself. The apparatus includes an arm member for supporting a fluoroscopic imaging device to be slidable along a circle centered around an isocenter; a supporting member for supporting the arm member to be rotatable in a vertical plane; and a carrier member for moving the support member in a horizontal plane, and for rotating the supporting member in the horizontal plane around a pivotal center not identical to the isocenter; where the carrier member, the supporting member, and the arm member are controlled such that the fluoroscopic imaging device can effectively be moved among positions distributed spherically around the isocenter, without changing an orientation of the supporting member with respect to the isocenter. The apparatus can also be effective in taking the fluoroscopic images of a region of interest in the object to be examined which requires more than one fluoroscopic imaging operations, without moving the object to be examined itself.
