Problems solved by technology

However, the existing technical schemes mainly adopt methods based on single-frame processing, or based on simple multi-frame linear filtering, and these solutions do not make full use of the motion characteristics of tissues in multi-frame images during the elastography process

Abstract

The invention relates to an ultrasound elastic imaging method and its system. The ultrasound elastic imaging system comprises a probe, a signal collecting module, a signal processing module and a multi-frame fusion module; the signal collecting module is used for collecting radio frequency data of a target object in a target zone; the signal processing module is used for acquiring displacement value of a current frame through mutual correlation operation according to the radio frequency data of the current frame and the radio frequency data of preset adjacent cached frames, and converting the displacement value of the current frame to a stress force of the current frame through gradient calculation; the multi-frame fusion module reads several strain force frames adjacent to the current strain force frame and acquires related elastic information of the target zone in relative to surrounding background zone through the multi-frame fusion treatment. The ultrasound elastic imaging method with the multi-frame fusion treatment is applied; the method and the system apply the feature that the movement direction consistence is available in multiple continuous images during the elastic ultrasound imaging process, thus the reliability and the accuracy of the strain force estimation are improved.

Description

technical field [0001] The invention relates to an ultrasonic elastography method and a system thereof, in particular to an ultrasonic elastography method with multi-frame fusion processing and a system thereof, belonging to the technical field of ultrasonic imaging. Background technique [0002] The elasticity or hardness of biological tissue is closely related to the biological characteristics of the lesion. Changes in the hardness or elasticity of biological tissue often imply the occurrence of lesions, which is largely related to the molecular composition and combination form of biological tissue. For the diagnosis of diseases It has important reference value. Clinically, palpation is the most commonly used method to detect the hardness and elasticity of biological tissues. Clinicians can directly squeeze the parts to be tested, and use the touch of fingers to determine the degree of hardening of tissues for detection and diagnosis, which is easy to infringe on patients....
