The research target is the non-invasive real time Doppler estimation of blood viscosity in the humans, to measure viscosity, shear stress, yield stress and shear strain rate. Unfortunately, blood viscosity is still measured invasively on blood samples, thus remaining a rarely investigated physical quantity. If widely available, it could allow easy categorization of patients in the hyper-viscosity syndromes. A theoretical reformulation of the Poiseuille, Oka and Casson equations from biorheometry, allows the computation of a great deal of non-newtonian viscosity curves. Non-invasive and invasive measurements (rotational viscometer) are then compared in order to validate the results.
