23 Jul Analysis system and method for obtaining stable state/transient state light diffusion characteristic
Abstract
The invention discloses an analysis method for obtaining stable state/transient state light diffusion characteristic, which belongs to the field of optical detection in biological and medical engineering science. The analysis method of the present invention utilizes easy-obtained optical parameters of each tissue in organism and light source parameters of optical detector, describes matrix of organism tissue structure and Monte Carlo model to calculate diffusion characteristic, employs a light transmission Monte Carlo method which is suitable for multi-voxel biological tissue, can be applied into organism with complicated three dimensional structure, and has higher accuracy and stability. The method sets two parameters of diffusion characteristic sampling frequency and sampling interval, introduces photon movement timing function into a recording module, and has characteristic of intelligently obtaining the stable state/transient state light diffusion characteristic. The invention also discloses a system for obtaining the stable state/transient state light diffusion characteristic, which includes a parameter input module, a tissue model input module, a diffusion characteristic calculation module, a diffusion characteristic recording module and a diffusion characteristic output module.
