Abstract
A three crystal ultrasound transducer in which each crystal has a thickness that is measured in the z-range direction that varies as a function of its position along the x-elevation direction. The impedance of the transducer is reduced compared with uniform thickness transducers thereby providing a better electrical match between the ultrasound transducer and the ultrasound system to which it is coupled.
