Modeling and validation of light propagation in free-space for non-contact near-infrared fluorescent tomography

Light propagation from the object boundary to detector was presented for non-contact near infrared fluorescent molecular tomography (FMT). Based on the work of Jorge Ripoll et al, perspective projection effect of lens was considered. The formula for light intensity transport in free-space was simplified. The relationship of the light intensity distribution on object boundary and the value obtained by CCD camera was established. Phantom experiment results confirm that this model is an efficient approach for non-contact near-infrared fluorescent molecular tomography.
