Most clinical ultrasound transducers are optimized for [[broadband]] pulses with center frequencies on the order of a few megahertz (MHz). The looks and characteristics of transducers used in [[medicine|medical]] [[Ultrasonic Imaging|ultrasonic imaging]] depend on the application and area of the body being imaged. For example, transducers used in [[heart|cardiac]] imaging must be designed so that the operator can avoid aiming the ultrasonic beam at the ribs and lungs, in which sound frequencies used to image the heart do not propagate well. Ultrasonic probes designed for bodily orifices must be shaped carefully so so as not to inflict internal damage when inserted. | Most clinical ultrasound transducers are optimized for [[broadband]] pulses with center frequencies on the order of a few megahertz (MHz).
