Abstract :
Optical coherence tomography (OCT) is a new technique mainly used in biomedical imaging. Here we present a particle-fixed Monte Carlo (PFMC) simulation for OCT. The scattering particles of the sample are assumed to be temporarily fixed randomly in the simulation process of backscattering light. The new model explains the exponential decay signal at the interface of different media layers in OCT experimental measurement. To extend the application area of OCT, an ultrasonic motor of 1 mm in diameter is used to implement the circular imaging scanning in OCT endoscopic probe
