Systems and methods for detecting regions of altered stiffness

摘要

An ultrasound imaging method for detecting a target region of altered stiffness is provided. The method comprises delivering at least one reference pulse to the target region to detect an initial position of the target region, delivering a first pushing pulse having a first value of a variable parameter to a target region to displace the target region to a first displaced position, delivering a first tracking pulse to detect the first displaced position of the target region, delivering a second pushing pulse having a second value of the variable parameter to the target region to displace the target region to a second displaced position, and delivering a second tracking pulse to detect the second displaced position of the target region. An ultrasound imaging system for detecting a region of altered stiffness is also provided.

1. An ultrasound imaging method for detecting a target region of altered stiffness, comprising:
delivering at least one reference pulse to the target region to detect an initial position of the target region; delivering a first pushing pulse having a first value of a variable parameter to the target region to displace the target region to a first displaced position; delivering a first tracking pulse to detect the first displaced position of the target region; delivering a second pushing pulse having a second value of the variable parameter to the target region to displace the target region to a second displaced position; delivering a second tracking pulse to detect the second displaced position of the target region; and detecting the target region of altered stiffness based on the first displaced position and the second displaced position of the target region.
