Tissue elasticity measurement method and device

A tissue elasticity measurement device, wherein the tissue elasticity measurement device comprises a control host of medical imaging and an elasticity measurement probe;

• the elasticity measurement probe is configured to transmit a first ultrasonic signal to a tissue in a measurement area, wherein the control host performs ultrasonic scanning by controlling N ultrasonic array elements on the elasticity measurement probe to form at least one imaging line of the first ultrasonic signal, wherein N is a positive integer;
• the control host is configured to track a measurement value of the at least one imaging line of the first ultrasonic signal;
• the control host is further configured to determine, according to the at least one imaging line at a plurality of time points, a motion state of each imaging line of the at least one imaging line, wherein the motion state is characterized by a plurality of motion parameters, the control host determines values of the plurality of motion parameters of each imaging line of the at least one imaging line according to the measurement value at the plurality of time points, when the values of the motion parameters meet a corresponding preset condition, it is determined that the motion state meets the preset condition;
• and
• the control host is further configured to select a position of the at least one imaging line with the motion state meeting the preset condition to determine one or more measurement positions of tissue elasticity measurement, the elasticity measurement probe is further configured to perform the tissue elasticity measurement at the one or more measurement positions, and an elastic parameter is obtained to diagnose a degree of tissue fibrosis.
