Abstract: A system and method for segmenting an anatomical structure in ultrasound imaging data. First ultrasound imaging data of a first region, which includes the anatomical structure, is acquired at a high resolution. Second ultrasound imaging data of a second region, which includes a region neighboring the first region, is acquired at a low resolution. The first and second ultrasound imaging data are processed to segment the anatomical structure.

Abstract: An ultrasound system produces maps of acoustic attenuation coefficients from pulse echo signals. Maps are produced using different attenuation coefficient or slope estimation methods, and a plurality of maps from different estimation methods are compounded to produce a final attenuation coefficient map. Confidence maps may also be produced for one or more attenuation coefficient maps, and the confidence map displayed or its measures used to determine weighting for the compounding process.
