8. The transducer convert one type of energy into
another based upon Pulse-echo principle where
electricity convert into sound called pulse, and
sound convert into electricity called Echo, the
transducer placed on the patient skin and emits high
frequency sound waves. When these sound waves
bounce off the organ or target part they create on
echo. The data created from echo is what makes up
image on the monitor.
