Abstract
A system and method for deriving information on disease in vascular segments for example mean pressure, drop in mean pressure and/or hydraulic resistance, from such measured waveforms is described. The waveforms can, for example, be measured non-invasively using Doppler ultrasound or magnetic resonance techniques. Form Factors (Vff, Pff) for the velocity waveform and the central arterial pressure are determined. Lesions may be detected and located using the estimated non-invasive hemodynamic information.
