COMPUTED TOMOGRAPHY SYSTEM COMPRISING ROTATABLE COLLIMATOR

摘要

Disclosed is a CT system with a rotatable collimator, which is a power semiconductor apparatus. The disclosed CT system has a gantry part including: an X-ray generating part capable of generating an X-ray; the rotatable collimator formed in the X-ray generating part, and limiting the irradiation area of the X-ray generated by the X-ray generating part; and an X-ray detecting part formed on the side of the X-ray generating part, wherein the collimator is capable of being rotated. According to the present invention, the CT system is capable of rotating only the collimator, thereby improving a rotation speed compared with rotating the gantry part entirely. In addition, the CT system is capable of reducing time to obtain the three-dimensional image of a target, and is capable of largely reducing an exposure dose to the target.
