Tumor classification based on an analysis of a related ultrasonic attenuation map

摘要

A computerized method of classifying at least one suspicious region of interest (ROI) in an ultrasonic attenuation image mapping tissue of a patient. The method comprises receiving an US image of an tissue, identifying a suspicious region of interest (ROI) in the US image, generating an attenuation map of the suspicious ROI, measuring, according to an analysis of the attenuation map, at least one attenuation feature of at least one of the suspicious ROI and at least one sub region in the suspicious ROI, and classifying the suspicious ROI according to the at least one attenuation feature.

1. A computerized method of classifying at least one suspicious region of interest (ROI) in an ultrasonic attenuation image mapping a tissue of a patient, comprising:
receiving an ultrasound (US) image of a tissue; identifying a suspicious region of interest (ROI) in said US image; generating an attenuation map of said suspicious ROI; measuring, according to an analysis of said attenuation map, at least one attenuation feature of at least one of said suspicious ROI and at least one sub region in said suspicious ROI, wherein said at least one attenuation feature is a ratio between the area of said suspicious ROI and a plurality of sub regions thereof with a pixel attenuation value above a predefined level; and classifying said suspicious ROI according to said at least one attenuation feature.
