What is an Ultrasound exam?
An Ultrasound is a diagnostic imaging exam that uses inaudible sound in the frequency range of approximately 20,000 to 10,000,000,000 cycles per second. Ultrasonic echoes are sent into the body by a transducer (probe). The transducer takes electric energy and changes it into acoustic pulses (echoes) that are sent into the patient. The echoes are then received back by the transducer as reflected echoes from the different interfaces of tissues and organs. A two dimensional gray-scale image is then produced by the computer.
