Relevant URL: Ultrasound is a low cost and real-time medical imaging modality.
However, traditional B-mode images have proved to be inefficient in
detecting and staging pathologies such as prostate cancer, limiting
the role of ultrasound as an anatomical guidance modality in clinical
interventions such as biopsy or brachytherapy. Active solutions (such
as elastography) and passive solutions such as feature extraction from
the raw RF ultrasound signals could augment the abilities of
ultrasound in tissue typing. In this talk, I will report my experience
and contributions with three of these approaches. These are: spectral
analysis of spatial segments of RF ultrasound signals, RF time series
analysis, and vibroelastography. Experimental results and Clinical
outcomes within the context of prostate cancer care will be provided.
