X-ray impinging position alignment method and x-ray tomographic imaging method and apparatus |
摘要 |
In order to make an X-ray impinging position coincide with a fixed position from the beginning of a scan, in scanning a subject to be examined by an X-ray emitting/detecting apparatus, an X-ray focus position is predicted based on the temperature of an X-ray tube 20 prior to beginning the scan and scan conditions intended to be currently used, and the position of a collimator 22 or an X-ray detector 24 is adjusted so that the X-ray impinges upon a fixed position on the X-ray detector 24. |
