Abstract

The invention provides an A-mode ultrasonic elastic imaging system based on mechanical scanning. The A-mode ultrasonic elastic imaging system comprises a three-dimensional motion control device, an A-mode ultrasonic probe, an A-mode ultrasonic instrument and an ultrasonic imaging device, wherein the A-mode ultrasonic instrument controls the A-mode ultrasonic probe to generate ultrasonic signals and receive ultrasonic echo signals; the three-dimensional motion control device drives the A-mode ultrasonic probe to mechanically scan an interesting tissue; and the ultrasonic imaging device re-establishes a two-dimensional or three-dimensional thromboelastogram. An imaging method of the A-mode ultrasonic elastic imaging system based on the mechanical scanning comprises the following steps of: step 1, squeezing the interesting tissue by the A-mode ultrasonic probe under different pressures, sending the ultrasonic signals, and mechanically scanning each point inside the interesting tissue twice, so as to form secondary ultrasonic echo signals; and step 2, re-establishing the two-dimensional or three-dimensional thromboelastogram of the interesting tissue by the ultrasonic imaging device according to elastic deformation amounts of the interesting tissue under the different pressures twice. The A-mode ultrasonic elastic imaging system has the advantages of high positioning precision, high sensitivity, high image resolution, strong practical applicability, wide application range and the like.

Description

technical field [0001] The invention relates to an ultrasonic elastography technology, in particular to a mechanical scanning-based A superelastic imaging system and method thereof. Background technique [0002] Ultrasound elastography is to obtain the waveform of ultrasonic echo signals under two different pressures at the same position in the region of interest through the probe, and use the two echo signals to perform correlation calculations to obtain the corresponding tissue elastic strain. Generally speaking, the probe scanning The pressure on the tissue, the speed of movement and the scanning direction will all have a certain impact on the elastography. For example, if the moving speed is too fast, the displacement and deformation of the tissue will be increased; if the pressure is too small, the displacement and deformation of the tissue will be reduced. Therefore, elastography must consider the impact of the three factors of probe scanning speed, scanning direction...
