3-D Digital flows in cerebrovascular phantoms

Abstract

Hemodynamic analyses of cerebrovasculature help in clinical diagnosis of various cerebrovascular diseases. Individual vascular geometry influence various hemodynamic factors as well as one's cerebrovascular health. In this work we present a new 3-D digital flow algorithm for quick simulation of hypothetical fluid flow in the mathematically in generated approximate cerebrovascular phantoms. The algorithm starts from a user initiated flow start point and iteratively wets the object region until convergence or a pre-defined end point is reached. We have also developed a customized 2-D/3-D user interface for initiation of fluid flow. After the termination of the algorithm, it delineates flow direction, flow velocity at each of the point of the object. The experimentation is done on several mathematically generated phantoms.
