Document Summary
8 transducers: a transducer is any device that converts one form of energy into. Ultrasound transducers perform two functions: during transmission, electrical energy from the system is, during reception, the reflected sound pulse is converted into converted into sound electricity. Some piezoelectric materials (quartz and tourmaline) are found in nature, but those commonly used in clinical transducers, lead zirconate titanate or pzt , are synthetic or man-made: synonyms: ceramic, active element, or crystal. Basic transducer construction: modern ultrasound transducers used in the clinical environment are elaborate. However, they share many of their design characteristics with simple, single crystal, unfocused probes. The design of these simple probes helps us understand transducer characteristics and function. 7 components: case: the cylindrical tube, constructed of metal or plastic, that, a basic ultrasound transducer has the appearance of a cylindrical tube. A sound pulse is emitted from the front of the tube, which is placed on the skin.
