Various approaches have been proposed to identify malignant breast tumors using ultrasound. In this study, we implement three different approaches and one combined method. Performance of these approaches is investigated based on simulation data. The three approaches are: video signal analysis (VSA), spectral estimation using periodogram (PER), and minimum side difference (MSD). Note that all approaches...
Sound-velocity inhomogencities degrade both the spatial resolution and the contrast in diagnostic ultrasound. We previously proposed an adaptive imaging approach based on the coherence of the data received in the channels of a transducer array, and we tested it on phantom data. In this study, the approach was tested on clinical breast data and compared with a correlation-based method that has been...
