Medical imaging transducers usually utilize a piezoelectric material as the active element to transform the electric input into a mechanical wave propagating into the imaging target and transform the echo back into electric output signal.
The addition of lead indium niobate PIN to PMN-PT crystals for higher transformation temperature has received much attentio. The ternary PIN-PMN-PT single crystal, due to its high coercivity and high depoling temperature, is a promising material for high frequency ultrasound transducers in medical imaging applications.
