摘要
电子计算机断层扫描 (简称CT),经20多年的发展技术上已相当成熟,应用范围已日趋扩大,由原来头、胸、腹与四肢,扩展到心脏在内的更大领域。特别是近年开发的多层面CT,是CT发展的新方向,也是高质量、高速度扫描万式的重大进步。由于它是一次扫描旋转过程中获得4个层面图像投影数据成像系统,对临床影像诊断意义明显,同时也是当今单层CT最有力的换代产品。
By twenty years development.the technic of computed tomography has comparatively
matured.At present, applicable areo of CT is not only including head,chest,abdomen,limbs but also heart.Multi-slice CT(MSCT)is a new developing direction,because it is a high-quality, high-speed scan mode and a imaging system that one scan may be get data of 4 slices. MSCT will substitute for single-slice CT.
