The terahertz pulse (THz pulse) propagation in biological tissue is simulated by Monte Carlo method (MCM). The migratory route of THz pulse in the tissue is presented. The computation model is based on the assumption that the refraction indexes of tissue and air are mismatch and both surfaces of the tissue have the reflection effect for THz pulse
Utilizing near-infrared spectroscopy for non-invasive blood component concentration sensing has been a focusing topic in biomedical optics applications. The ease of use, low cost and portability of these methods is a clear advantage over the invasive blood component concentration sensing which is the main sensing method in the clinic application. However, there is no report about any successful non-invasive...
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...
