In this work we show that for imaging tissue with low scattering background, reconstruction algorithms using derivatives calculated through perturbation Monte-Carlo method worked well whereas diffusion equation based methods failed. An easy way to estimate the Jacobian using analytical expression obtained from perturbation Monte-Carlo method is demonstrated. We have successfully reconstructed both absorption- and scattering inhomogeneities in objects, which fall under transport equation regime. Experimental data gathered from tissue-equivalent phantoms with low-scattering coefficient background and absorption and/or scattering inhomogeneities are reconstructed using the above method.
