Abstract EN
Bioluminescence tomography (BLT) is a molecular imaging modality which can three-dimensionally resolve the molecular processes in small animals in vivo.
The ill-posedness nature of BLT problem makes its reconstruction bears nonunique solution and is sensitive to noise.
In this paper, we proposed a sparse BLT reconstruction algorithm based on semigreedy method.
To reduce the ill-posedness and computational cost, the optimal permissible source region was automatically chosen by using an iterative search tree.
The proposed method obtained fast and stable source reconstruction from the whole body and imposed constraint without using a regularization penalty term.
Numerical simulations on a mouse atlas, and in vivo mouse experiments were conducted to validate the effectiveness and potential of the method.
