Fluoroscopic radiographing carrier apparatus

摘要

An X-ray tube device is rotated to a projected portion in a subject by a rotating mechanism for the X-ray tube device according to an operation for an oblique fluoroscopy. A CPU recognizes information about a rotating angle and rotation speed, and a stand for the X-ray tube is moved along a longitudinal direction of a top plate by a driving mechanism for the stand according to the information. An X-ray image detector disposed under the top plate is moved in a direction opposite to the movement of the stand to a corresponding position of the X-ray tube device by a driving mechanism for the X-ray image detector. The X-ray tube device, the projected portion in the subject and the X-ray image detector are always arranged in a straight line by the CPU and the independent driving mechanisms. A tomography may also be carried out by moving continuously the X-ray tube device and the X-ray image detector parallel to the top plate in the opposite directions.
