2004 the sixth period · medical equipment computed tomography (CT) clinical application of more than 30 years of history. During this period, CT developed rapidly in both hardware and software technologies. From the initial scanning of about 2 minutes in a single layer to image reconstruction in about 7 minutes and low-resolution images, CT has developed into today's large-volume multi-slice spiral rapid scanning. Real-time images Reconstruction techniques and in the shaft, crown, sagittal position obtained
