Ultrasound is one of the most widely used diagnostic procedures available. It provides a safe, non-invasive and virtually painless means of observing soft tissue anatomy on an outpatient basis.
Because it can be used in the most delicate conditions without major side effects, ultrasound has become one of the most popular diagnostic methods among both patients and physicians. Diagnostic ultrasound allows physicians to diagnose without invading the body with dyes, radiation or exploratory surgery.
Ultrasound imaging is based on the same principles involved in the sonar used by bats. During an exam, a sonographer moves a transducer over the part of the body to be imaged. The transducer functions as both a loudspeaker (to create the sounds) and a microphone (to record them). High-frequency sound waves reflect off internal structures (soft tissue, organs and blood flow), producing echoes that are processed into an image displayed on the ultrasound system monitor.
