Characterization of Medical Ultrasound Transducers [PDF]
2018 IEEE International Ultrasonics Symposium (IUS), 2018 Optimal use of multi-element ultrasound transducers requires knowledge of the performance of their individual elements, for realistic simulation and optimized beamforming. When developing transducers, it is critical to characterize the performance of the transducer material itself, removing the effect of the transducer element size and geometry.
