New modified Butterworth Van-Dyke model for high frequency ultrasonic imaging

For ultrasonic transducers, a number of equivalent circuit models including KLM, Mason and Butterworth Van Dyke (BVD) have been developed. To allow them to be incorporated into design tools for complex integrated circuits, KLM or Mason models are not practical because the discrete components of the equivalent circuits have negative values. Therefore, BVD model appears to be more appropriate but it needs to be improved because the resolution of a high frequency ultrasound system may be severely affected by impedance mismatching between the transducer and the system, as well as attenuation due to parasitic impedances of the systems. A new modified BVD model has been developed and the results demonstrate its usefulness in modeling high frequency ultrasonic transducer and its imaging systems.
