Problems solved by technology

However, in the application of this method, the shear wave generated inside the tissue is relatively weak, and the propagation of the shear wave in the tissue is a transient process, and the shear wave will attenuate and disappear after a certain time and a certain distance, so it must be Rapid and large-area extraction of shear wave information within a period of time requires high requirements for shear wave extraction, and the data processing load of the extraction system for shear wave extraction is relatively large, and the accuracy is low

Abstract

The invention provides a shear wave imaging method. The method comprises the following steps of: generating shear wave inside a tissue; pre-estimating the shear wave, sending a plurality of tracking pulses corresponding to positions of the shear wave at different moments, and receiving echo information of the tracking pulses; carrying out shear wave parameter calculation according to the echo information of the tracking pulses; and imaging and displaying the result of the shear wave parameter calculation. According to the shear wave imaging method and system provided by the invention, the detection positions of the shear wave is estimated in advance, so that the detection of the shear wave can be accurately carried out in a small range, the detection energy is relatively concentrated, andthe detection signal-to-noise ratio is improved. Meanwhile, the redundant detection times are reduced, the detection process is accelerated, and the data processing burden is reduced. The invention also provides a shear wave imaging system.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to a shear wave imaging method and system. Background technique [0002] Ultrasound elastography is one of the hotspots of clinical research in recent years. It mainly reflects the elasticity or hardness of tissues. It has been increasingly used in the auxiliary detection of tissue cancer lesions, the distinction between benign and malignant, and the evaluation of prognosis and recovery. An existing ultrasonic elastography uses shear waves to perform imaging, mainly by generating shear wave propagation inside the tissue and detecting its propagation parameters and imaging, thereby reflecting the difference in hardness between tissues. [0003] This method has better stability and repeatability. However, in the application of this method, the shear wave generated inside the tissue is relatively weak, and the propagation of the shear wave in the tissue is a transient process, and th...
