Detection of Arterial Occlusions Using Viscoelastic Wave Propagation

Inverse problems, viscoelastic models, wave propagation in biotissue, statistical models.Abstract
We consider the problem of detecting cardiac artery occlusions using stenosis driven viscoelastic (VE) waves propagated through biotissue to body surface sensors. We investigate possible statistical model formulations (ordinary least squares (OLS), generalized least squares (GLS)) and post analysis techniques (residual plots) to ascertain uncertainty in estimates as well as validity of the statistical models as part of a methodology for stenosis detection using viscoelastic waves.
