摘要：We present an approach based on the improved Levenberg
Marquardt (LM) algorithm of backpropagation (BP) neural network to estimate the
light source position in bioluminescent imaging. For solving the forward problem, the
table-based random sampling algorithm (TBRS), a fast Monte Carlo simulation method
we developed before, is employed here. Result shows that BP is an effective method to
position the light source.
