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.
