Abstract:
Totally digitalized B-ultrasonography is the tendency of the development of ultrasonic medical instruments. Its basic technical characteristic is realizing real-time processing of the extremely huge ultrasonic data with digital electric circuit. This paper summarized the tendency of development and the primary techniques of signal processing, which including dynamic filtering, log amplification, envelope detection and secondary sampling. Furthermore, various techniques in different procedure of signal processing are introduced in detail.
