Abstract
Non-invasive vascular ultrasound has been introduced in patient specific cardio/cerebro-vascular risk evaluation, treatment efficiency estimation, and drug-development strategies. The ultrasound measurement system is based on analysis of radio frequency echo data and is usually combined with evaluations of textural, contextual, morphological and clinical features in a multi-parameter approach. Processing of radio frequency data enables individual vascular risk evaluation depending on the clinical purpose. The non-invasive nature of radio frequency based techniques makes them suitable for screening large populations, and evaluation of drug efficiency in vascular risk reduction.
