PURPOSE:To flexibly perform scanning for setting the positions of a radiation generator and a radiation detector and collecting the data of an object to be examined, by correcting a scanning track to a scheduled track by measuring the position of a radiation generated point. CONSTITUTION:A radiation detector 43 and radiation generated point position detection means 45A, 45B are connected to CPU71 through a data collection part 44. The radiation generated point position detection means 45A, 45B are provided to both sides of the radiation detector 43 and calculate the position of the radiation generated point (a) of the radiation detector 43 and collect data while corrects a track to perform re-constituted image processing. Therefore, it is unnecessary not only to anchor an X-ray tube and an X-ray detector with high accuracy but also to rotate a rotary table and a rotary drive system while round is always kept. |
