Angle-Dependent Transport Theory-Based Ray Transfer Function for Non-Contact Diffuse Optical Tomographic Imaging

This work presents a generalized angle-dependent ray transfer function that can accurately map the angular and spatial distribution of light intensities on tissue surface onto camera image plane in non-contact camera-based imaging system. The method developed here goes beyond existing models apply to angle-averaged tomographic data alone. operator was constructed using backward tracing based radiation theory. proposed validated numerical phantoms experimental from an actual
