Multilayer tubular phantoms for optical coherence tomography

摘要

We report preliminary results toward making artery phantoms for Optical Coherence Tomography (OCT) that also exhibit mechanical properties similar to arteries for large deformation regimes. A matrix of PVA cryogels is used to obtain the strain hardening effect characteristic of arteries. Means of adjusting the optical properties of PVA cryogels are investigated and the resulting mechanical properties are characterized.
