Enhanced shock scattering histotripsy with pseudo-monopolar ultrasound pulses
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control(2019)
摘要
Shock scattering histotripsy involves a complex interaction between positive and negative phases of an acoustic burst to initiate a robust cavitation bubble cloud. To more precisely study these effects and optimize shock scattering histotripsy therapy, we constructed a frequency compounding transducer to generate pseudomonopolar ultrasound pulses. The transducer consisted of 113 individual piezoel...
