Light field particle image velocimetry by plenoptic image capturing for 3D-display of simulated blood flow in cerebral aneurysms

Abstract

Particle image velocimetry of simulated blood flow within transparent 3D resin models of cerebral aneurysms allows 3D real-time simulation of the flow-dynamics with and without implants as a new pre-interventional opportunity for endovascular treatment. The purpose of the experiments is to demonstrate the feasibility of 3D-flow visualization in small volumes (below 5 mm diameter) of particle flow although capturing the flow dynamics by a monocular camera set-up.
