<P>PROBLEM TO BE SOLVED: To provide a system and method for detecting a region where rigidity has been changed. <P>SOLUTION: An ultrasonic imaging method for detecting a target region where the rigidity has been changed comprises a process to transmit a reference pulse to the target region so as to detect the initial position of the target region, a process to transmit a first pushing pulse having a first value of a variable parameter so as to displace the target region to a first displacement position, a process to transmit a first tracking pulse so as to detect the first displacement position of the target region, a process to transmit a second pushing pulse having a second value of the variable parameter so as to displace the target region to a second displacement position, and a process to transmit a second tracking pulse so as to detect the second displacement position of the target region. The ultrasonic imaging system for detecting the region where the rigidity changed is also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
