We present a full three-dimensional, featured-data algorithm for time-domain fluorescence diffuse optical tomography that inverts the Laplace-transformed time-domain coupled diffusion equations and employs a pair of appropriate transform-factors to effectively separate the fluorescent yield and life

Digital radiography (DR) and whole-body fluorescent optical imaging (WFOI) have been widely applied in the field of molecular imaging, with the advantages in tissues and functional imaging. The integration of them contributes to the development and discovery of medicine. We introduce an equipment, performance of which is better than that of another molecular imaging system manufactured by Kodak Corp. It can take real-time small animal imaging in vivo, with lower cost and shorter development cycl
