System and method for tissue characterization using ultrasound imaging

摘要

An ultrasound system comprises an ultrasound probe for transmitting transmit beams and receiving receive beams. A processor controls the ultrasound probe to direct the transmit beams in a first direction to acquire a first incidence frame of data and a second direction to acquire an second incidence frame of data, wherein the first and second directions are different with respect to each other. A tissue characterization module compares the normal and oblique incidence frames of data to determine at least one property parameter of a scanned medium based on amplitude differences between the receive beams.

1. An ultrasound system, comprising:
an ultrasound probe for transmitting transmit beams and receiving receive ultrasound beams; a processor for controlling the ultrasound probe to direct a first plurality of transmit beams at a first angle to acquire a first incidence frame of data and a second plurality of transmit beams at a second angle to acquire a second incidence frame of data, wherein the first and second angles are different with respect to each other; and a tissue characterization module for comparing the first and second incidence frames of data to determine relative tissue stiffness of a scanned medium based on differences between the received ultrasound beams, wherein the tissue characterization module subtracts the first and second incident frames of data to determine the differences.
