西德“科技展望”1981年第16期认为:超声计算机断层显示技术具有良好的前景,将成为未来的诊断手段. 计算机断层显示是一种记录和显示断面图象的方法.X射线断层显示早已为人们所熟知.据认为,超声技术开辟了断层显示技术的新阶段.因为超声透视是非电离化的照射,在小剂量下对人体绝对没有损害.超声断层显示的另一个优点是不需要对比手段,而这在某些X射线方法中是必不可少的. West Germany “Technology Outlook” 16th in 1981 that: ultrasonic computed tomography display technology has good prospects, will become the diagnostic tool in the future .Computed tomography is a method of recording and displaying cross-sectional images.X-ray tomography has long been Is well known.It is believed that the ultrasound technology has opened up a new phase of the tomographic display technology because ultrasound fluoroscopy is non-ionizing radiation, which is absolutely harmless to the human body at low doses.Another advantage of ultrasound tomography is that it does not require contrasting means , Which is essential in some X-ray methods.
