Medical diagnostic ultrasound method and system for contrast specific frequency imaging

摘要

A medical diagnostic ultrasound imaging method and system insonify a tissue containing a contrast agent with ultrasonic transmit signals at a fundamental frequency f. Backscattered ultrasonic receive signals are acquired and filtered to emphasize frequency components between the fundamental frequency f and the second harmonic frequency 2f, and the filtered receive signals are processed for display. This filtering enhances the ability of the method and system to discriminate between contrast agent and adjacent tissue.
