CT自 2 0世纪 70年代问世以来有了突飞猛进的发展 ,近年来随着滑环技术、螺旋式扫描技术、超高速CT技术的发展 ,使CT检查技术已提高到了一个崭新的水平。常规CT、螺旋CT(SpiralCT ,SCT)、电子束 (electronbeamCT ,EBCT)、多排螺旋CT(Multi slicesspiralCT ,MSCT)或称多排探测器
CT has developed rapidly since the advent of the 1970s. In recent years, with the development of slip ring technology, spiral scanning technology and ultra-high speed CT technology, CT scanning technology has been brought to a whole new level. Conventional CT, Spiral CT (SCT), electron beam CT (EBCT), multi slice spiral CT (MSCT) or multi-row detector
