Abstract
We explore the potential of intravascular or endoscopic optical coherence tomography (OCT) to extract relevant mechanical properties of a tissue deformed by an inflating balloon. Tubular OCT phantoms with different mechanical properties are fabricated. The phantoms are deformed by an inflating balloon, and the deformation is monitored with OCT. A quantitative description of the phantom deformation is obtained by segmenting the OCT images. Two strategies to extract the mechanical properties from this quantitative data are presented: by comparing to a finite-element simulation and by performing a mechanical analysis.
