Abstract

The invention discloses an ultrasonic elastography system and method. The ultrasonic elastography system comprises an elastic detection module for processing a beam-forming output signal, calculating the elasticity physical quantity of a target to be detected and generating a corresponding elastic image according to the physical quantity, a parameter calculating module for calculating a compression parameter corresponding to the elastic image, a display module for displaying the elastic image and the corresponding compression parameter, wherein the compression parameter is used for reflecting the detected target compression degree of a probe. The ultrasonic elastography system can display the corresponding compression parameter while displaying the elastic image, a user can intuitively judge whether the compassion degree of the probe to the target to be detected is required to be adjusted or not, accordingly a certain guidance is provided for the user, especially for a user lack of operational experience, and the operation is simple and convenient.

Description

technical field [0001] The present application relates to ultrasound imaging technology, in particular to an ultrasound elastography system and method. Background technique [0002] Ultrasound elastography is a commonly used ultrasonic imaging technology. Its basic principle is: slightly compress the target tissue with the probe or form a certain pressure on the tissue with the help of the human body's own breathing, vascular pulsation, etc., and obtain two frames of ultrasonic echoes before and after compression. Wave signal, when the tissue is compressed, a strain along the compression direction will be generated in the tissue, if the distribution of Young's modulus in the tissue is not uniform, the strain distribution in the tissue will also be different; then the strain of the tissue will be detected by some methods The information is output to the interface and displayed visually in the form of elastic images. The quality of the output elastic image is affected by the ...
