Method and system for lesion detection in ultrasound images

An ultrasound system comprising:

• an ultrasound transducer for transmitting and receiving ultrasound signals to and from an area of interest;
• a receiver for receiving the ultrasound signals;
• and
• a processor coupled to the ultrasound probe, the processor programmed to:
• acquire an ultrasound image;
• generate a Fisher-tippett (FT) distribution-based edge feature map from the acquired ultrasound image;
• generate gradient concentration (GC) scores for pixels of the acquired ultrasound image using the FT distribution-based edge feature map;
• and
• identify a candidate lesion region within the acquired ultrasound image based on the GC scores.

A method for detecting lesions in ultrasound images, said method comprising:

• identifying a candidate lesion region within an ultrasound image;
• calculating multi-scale topological texture features for the candidate lesion region from the ultrasound image;
• and
• classifying the candidate lesion region as a lesion or normal tissue using a classifier.
