Durable optical phantoms with complex geometries and tissue-likemechanical properties

摘要

In this paper, we present an approach toward the creation of coronary artery phantoms for optical coherence tomography (OCT). By mixing alumina powder in a matrix of transparent silicone, it is expected that the amplitude of the OCT signal and the soft tissue elasticity can be reproduced. The fabrication process to produce such multiple layer phantoms is presented along with optical and characterization experiments.
