PURPOSE:To obtain a tomographic equipment capable of obtaining a tomographic image of high image quality. CONSTITUTION:A turntable 8 having a subject 9 placed thereon, the traverse frame 10 operated through a traverse mechanism 11 and the up-and-down movable frame 5 driven through an up-and-down motion mechanism 6 are controlled by a mechanism control unit 12 and the subject 9 is set in many-arrangement with respect to X-ray fan beam 3. The output data of a detector 4 in this arrangement of the subject 9 are collected by a data collecting device 14 and the collected output data are combined by a reconstitution device 15 to perform processing adding and averaging the data related to the transmission paths passing one point of one focal surface at different angles with respect to all of points and the tomographic image focused on one focal point of the subject 9 is formed. |
