Abstract-
For near infrared imaging of neonatal head surrounded by cerebrospinal fluid layer, we have developed an imaging modality, which uses perturbation Monte-Carlo estimation of Jacobian of the forward model for photon propagation. In this case, we have shown that the conventional techniques, which uses diffusion approximation for light transport in tissue, fails to give the reconstruction of tissue optical properties. We were able to successfully reconstruct both scattering- and absorption inhomogeneities' in objects which fall under the transport regime. Results of numerical simulation are presented
