Tissue imaging at superharmonic frequencies

摘要

Ultrasound imaging of tissue in medical applications is carried out by transmitting ultrasound energy into a target volume at least a first fundamental frequency, receiving reflected and/or scattered ultrasound energy from the target volume; and detecting components of the received signal at multiple harmonics of the fundamental frequency or at one or more of the third to fifth harmonics of the fundamental frequency. A image of the target volume is generated using the detected harmonic components of the received signal.
