Abstract: A quantitative ultrasound (QUS) system for characterizing a specimen, the system comprising an ultrasound transducer operable to transmit ultrasound signals into the specimen along multiple adjacent scan lines extending axially within the specimen, and collect returned ultrasound signals therefrom and generate RF signals based on said returned ultrasound signals, wherein said RF signals are associated with respective ones of said scan lines to represent a characteristic of the specimen at each of multiple locations within the specimen along each of said scan lines; and a parallelizable processing unit communicatively coupled to said ultrasound transducer and operable to concurrently compute from said RF signals respective QUS values representative of said characteristic for each of a plurality of said multiple locations in parallel, wherein successive parallel outputs of said respective QUS values are characteristic of the specimen along each of said multiple scan lines.
