The invention provides a multi-dimensional elastosonography detecting device of the liver, comprising a probe, a signal processing unit, a control unit and a computer, wherein the signal processing unit is electrically connected with the probe; the control unit is electrically connected with the signal processing unit; the computer is electrically connected with the signal processing unit and thecontrol unit; the probe is placed on the body surface of the liver, measures elastic modulus of the tissue of the liver and sends an echo electric signal to the signal processing unit; the signal processing unit processes the echo electric signal received by the probe and transmits the processed signal to the computer; the control unit controls the functions of the probe and the signal processingunit, acquires operation instruction of a user and simultaneously returns the needed instruction and data to the computer; and the computer processes the data transmitted by the signal processing unit and the control unit and obtains and displays the two-dimensional distribution of the elastic modulus of the tissue of the liver on a plane. The invention also relates to a multi-dimensional elastosonography detecting method of the liver.
Description
technical field [0001] The invention relates to a medical device, in particular to a liver multi-dimensional ultrasonic elasticity detection device and a detection method thereof. Background technique [0002] Human liver fibrosis is a common pathological basis of many liver diseases, especially chronic liver diseases. If left unchecked, it may eventually lead to liver cirrhosis or even liver cancer. Early diagnosis and quantification of the development degree of liver fibrosis are important for timely intervention and reversal of its development. significance. Traditional imaging methods are difficult to find signs of liver fibrosis, especially early liver fibrosis, and ultrasound elastography can be used to speculate in real time by sending low-frequency vibration shear waves into the body and using ultrasound to detect the propagation speed of shear waves in liver tissue. The elastic modulus of the liver was obtained, which was used as the quantitative basis for the degr...
