Abstract

Pressure changes caused by an ultrasound pattern inside tissue will modify its density and hence its refractive index. We present an integrated computational imaging approach to minimize multiple-scattered reflected light from tissue. It is based on optimum modulation of the refractive index of tissue using an ultrasound pattern. We examine issues related the design of such pattern using COMSOL Multiphysics. An optimum ultrasound pattern could be used to design and implement an integrated- computational optical coherence tomography (IC-OCT) system with extended depth of imaging.
