主　　题：photon resolved analysis 

摘      要：In this study,time resolved(TR)Monte Carlo(MC)simulation program code was run to generate photon fluencies with increasing time *** MC simulation was performed for ten time series from 4 ps to 52 *** photon fluencies were transferred to the image analysis programming *** device geometry was created for test purpose in image reconstruction programming platform *** model weight matrix functions were calculated during each time period for 38 sources,and 38 detectors according to the back-reflected imaging geometry.A homogenous phantom,which simulated tissue,was *** on the homogeneous tissue optical properties,such as tissue absorption coefficientμa,and tissue scattering coefficientμs,photons emitted from the laser source positions;migrated differently inside the imaging *** migrate inside the tissue by some multiplication factor of ps depending on the tissue type for each 100-micrometer vertical *** photons come photodetector point fast,depend on the source-detector neighborhood distances and tissue optical properties,*** resolved diffuse optic tomography(TRDOT)imaging systems are an emerging biomedical optic imaging modality due to progressive electronic technologies are helping to build the systems faster and *** such,emerging microelectronic technology is giving important access to design and implement compact laser sources and photodetector *** cavity surface emitting light(VCSEL)as laser source and single photon avalanche diode(SPAD)arrays as photodetector units are becoming in common use as important hardware tools for designers and researchers in this *** diffuse photon analysis should be done routinely for better understanding of TRDOT ***,MC simulation driven TR photon fluence analysis was done for such a purpose in this study.
