We have computed predistorted pulses that minimize tissue harmonics to < -25 dB compared to fundamental over a 4-cm depth in the focal region using a Hankel transform-based algorithm. The results indicate their potential in achieving patient independent improvement in contrast with microbubbles using wideband ultrasonic transducers at high mechanical indices.
