Abstract

A method for eliminating background noises in shear waves and the respective ultrasonic imaging system, the method includes: transmitting a push pulse along a push pulse vector; transmitting a first group of focus track pulses at a first group of a plurality of locations far away from the push pulse vector; receiving a first group of focus echo signals in response to the first group of focus track pulses; and processing the first group of focus echo signals to determine a first group of tissue displacement information varying with time.

Description

technical field [0001] The present invention generally relates to the field of ultrasonic testing, and more particularly to a method, device and ultrasonic imaging system including the device for eliminating background noise in shear waves. Background technique [0002] Ultrasonic testing is a commonly used testing method in the modern medical field. [0003] When sound waves propagate in a heterogeneous medium, an acoustic pulse radiation force (Acoustic radiation force) is generated. Acoustic pulse radiation forces can characterize the biomechanical elasticity of tissues. This has sparked research interest in the fields of materials science and medical diagnostics. [0004] One of the long-sought goals of diagnostic imaging is the accurate characterization of tissue. A clinician wants to obtain a diagnostic region of a body organ and have the imaging system identify features of the tissue in the image. Ideally, clinicians would like the imaging system to identify wheth...
