2.6 System Principle
The fundamental operating principle of diagnostic ultrasound system is:
through the transducer, electric excitation signals are converted into acoustic
signals, which are propogated, attenuated and reflected in the patient’s body.
Then the echos from the body are converted into electric signals through the
transducer. Going through complicated signal processing circuit, a scanned
tomographic image is displayed on the monitor.
The block diagram of the system is displayed below:
