Abstract
Disclosed is a method for extracting quantitative information by a device operated by at least one processor. The method includes: receiving pulse-echo data obtained from sensors of an ultrasound probe according to beam patterns radiated into a tissue; obtaining a location of a region of interest (ROI); and extracting quantitative information on the ROI from the pulse-echo data by using a neural network trained to extract quantitative information from input data.
