Method, apparatus, and system for measuring propagation of shear wave using ultrasound transducer

摘要

A method of measuring propagation of a shear wave by using an ultrasound transducer includes generating a shear wave inside the object, setting a region of interest (ROI) on which propagation of the shear wave is to be observed, and determining a position of a second focus on which ultrasound signals are to be directed to obtain information about the ROI, irradiating the ultrasound signals toward the second focus, and receiving echo signals reflected from the ROI.

1. A method comprising:
generating a shear wave inside an object at a first focus; setting a region of interest (ROI) on which propagation of the shear wave is to be observed and at which the shear wave maintains an amplitude above a predetermined level; setting a margin based on a distance from a plurality of transducers of an ultrasound probe to the ROI and a wavelength of ultrasound signals to be irradiated by the plurality of transducers of the ultrasound probe; setting, based on a width of the ROI and the margin, a position of a second focus on which the ultrasound signals are to be irradiated to obtain information about the ROI; controlling the plurality of transducers of the ultrasound probe to irradiate the ultrasound signals toward the second focus; and receiving, by the plurality of transducers of the ultrasound probe, echo signals from the ultrasound signals irradiated toward the second focus and reflected from the ROI.
