英文摘要Purpose: Bioluminescence tomography (BLT) is a promising in vivo optical imaging technique in
preclinical research at cellular and molecular levels. The problem of BLT reconstruction is quite
ill-posed and ill-conditioned. In order to achieve high accuracy and efficiency for its inverse
reconstruction, we proposed a novel approach based on 
Lp regularization with the Split
Bregman method.

Procedures: The diffusion equation was used as the forward model. Then, we defined the
objective function of 
Lp regularization and developed a Split Bregman iteration algorithm to
optimize this function. After that, we conducted numerical simulations and 
in vivo experiments to
evaluate the accuracy and efficiency of the proposed method.

Results: The results of the simulations indicated that compared with the conjugate gradient and
iterative shrinkage methods, the proposed method is more accurate and faster for multisource
reconstructions. Furthermore ,
in vivo imaging suggested that it could clearly distinguish the
viable and apoptotic tumor regions.

Conclusions: The Split Bregman iteration method is able to minimize the Lp regularization
problem and achieve fast and accurate reconstruction in BLT.
