Abstract: An ultrasound system and method are provided for detecting lesions and/or abnormalities in a heterogeneous medium. An array of ultrasound transducer elements configured to emit ultrasound signals and to receive backscattered ultrasound signals. A processor performs a lesion detection algorithm that processes the backscattered ultrasound signals to obtain an Inter-element Response Matrix (IRM), splits the IRM into a plurality of sub-IRMs corresponding to subsets of the ultrasound transducer elements, and then performs additional processing that includes performing a depression detection algorithm to identify one or more lesions and/or abnormalities.

Abstract: Methods, systems, and computer readable media for utilizing ultrasound multiple scattering to assess pulmonary fibrosis are disclosed. One method may comprise transmitting ultrasound energy into the lungs of a subject, detecting portions of the ultrasound energy backscattered by structures in the lungs of the subject, calculating a transport parameter from the detected portions of the ultrasound energy backscattered by the structures in the lungs of the subject, inputting the transport parameter into a model that correlates values of the transport parameter with quantitative indications of severity of pulmonary fibrosis, and receiving, from the model, a quantitative indication of the severity of pulmonary fibrosis for the subject that correlates with the transport parameter for the subject.
