Ultrasound Physics: SPI

The fundamental or operating frequency - is affected by the thickness of the PZT element Which could not be used as the coupling medium (gel)? - barium sulfate The piezo electric effect is best described as - deformation from voltage sent to the crystals How thick is the element if the frequency is 3 MHz? - half the wavelength of the wave in the PZT The gel has greater impedance that the matching layer but less than the impedance of the PZT elements' - false The impedance of the PZT cryst...
