What is ultrasonic imaging?.
A Primer of Diagnostic Ultrasonic Imaging
What is ultrasonic imaging?Ultrasonic imaging is the transmission of very high frequent inaudible sound waves into the body by an ultrasonic transducer, then receiving echo information for tissue structures with the same transducer. The echo information is then electronically processed to form a viewable image of the tissue structures. This is very similar to to the sonar process used in the Navy for finding underwater objects.

Why?
Diagnostic ultrasonic imaging is used by doctors to view internal body structures for the diagnosis of diseases, abnormality of structures, and even blood flow.
