Abstract

Optical coherence tomography (OCT) is a technique that is widely used to diagnose pathologies through morphological changes in tissue structure. OCT imaging of such structures based on the backscattered intensity provides qualitative images that are not quantitatively related to the tissue’s optical properties. Since certain pathologies affect optical parameters of tissues, such as the attenuation coefficient, quantification of the attenuation coefficient could be useful for medical diagnosis [1]. For accurate quantification of optical parameters robust depth resolved OCT m odels, which are valid over a wide range of parameters are necessary. In order to investigate and test such models a novel Monte Carlo (MC) simulation method for OCT, that takes the confocal function into account was developed. To validate the MC model it is compared to OCT measurements on optical phantoms executed by Kübler et al.[2].
