Tissue elasticity detection method, device and system

Abstract

The embodiment of the invention provides a tissue elasticity detection method, device and system. The method comprises the steps: obtaining a contact parameter between a detection probe and a to-be-detected object, the contact parameter being used for representing the contact degree between the detection probe and the to-be-detected object; if the contact parameter meets a first threshold condition, controlling the detection probe to transmit and receive an ultrasonic signal to the to-be-detected object so as to determine a target detection position of the to-be-detected object; and if the contact parameter meets a second threshold condition, controlling the detection probe to perform shear wave excitation on the target detection position of the to-be-detected object so as to measure the elasticity of the target detection position of the to-be-detected object. According to the embodiment of the invention, an operator can accurately judge the opportunity of ultrasonic signal emission and shear wave excitation, so that the stability and accuracy of a measurement result are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of measurement technology, and in particular to a tissue elasticity detection method, device and system. Background technique [0002] Ultrasound imaging and elastography are widely used in medical care and other fields. Usually, the detection probe is used to emit ultrasonic signals (such as: A-ultrasound, M-ultrasound, or B-ultrasound signals) for ultrasonic image guidance to initially determine whether the current detection position is the detection object The position and whether there is interference, after obtaining the position of the detection object, perform shear wave excitation (such as: mechanical wave or shear wave signal), and measure the elasticity of the detection object. Combining the above two detection methods can realize real-time Quickly obtain the position of the detection object, and obtain the elasticity of the detection object through elasticity measurement.
