METHOD AND APPARATUS FOR DETECTING ULTRASONIC MEASUREMENT DEPTH OF ULTRASONIC ELASTICITY MEASUREMENT INSTRUMENT HAVING IMAGE GUIDE FUNCTION

摘要

Disclosed are a method and apparatus for detecting an ultrasonic measurement depth of an ultrasonic elasticity measurement instrument (200) having an image guide function. The ultrasonic elasticity measurement instrument (200) is used for measuring the elasticity of elastic tissue in an ultrasonic pulse-echo mode by means of a mechanical vibrator generating low-frequency vibration. The method comprises: carrying out, on a test phantom (300), ultrasonic pulse transmission that conforms to an image guide type, wherein the phantom (300) is provided with a target spot at a predetermined depth; receiving an echo signal generated by the target spot for an ultrasonic signal; and calculating the maximum depth of the target spot according to the echo signal, so as to determine an ultrasonic measurement depth of an ultrasonic elasticity measurement instrument (200).
