Image reconstruction for bioluminescence tomography from partial measurement

Abstract: Abstract:The bioluminescence tomography is a novel molecular imaging technology for small animal studies. Known reconstruction methods require the completely measured data on the external surface, although only partially measured data is available in practice. In this work, we formulate a mathematical model for BLT from partial data and generalize our previous results on the solution uniqueness to the partial data case. Then we extend two of our reconstruction methods for BLT to this case. The first method is … Show more

“…The configuration of the phantom and form of sources used for numerical experiments are the same as in our previous study [9]. Due to the limited space, we only report representative reconstruction results of S-BLT with the EM algorithm as the underlying inner-loop iterative algorithm.…”

“…However, BLI only works in 2D imaging mode which is mainly qualitative and incapable of 3D imaging in practice. To overcome limitations of BLI, bioluminescence tomography (BLT) was introduced [6] to perform quantitative 3D reconstruction of bioluminescent source distributions in vivo and has undergone intensive research since [7][8] [9][10] [11].…”

“…Many important results in this area are bought out by several groups in the world [5,7,12,16,17]. However, BLT is still faced with challenge, such as more accurate mathematical model, the improvement of the reconstruction algorithm, the deeper depth reconstruction of small animal, and so on.…”

“…Although the problem size can be reduced by allowing sources only in a permissible region (Cong et al 2004, 2005, Wang et al 2006a, 2006b, Jiang et al 2007, Lv et al 2007, we do not consider such constraints here. In (11), L is the data-fit function (12) β is a regularization parameter, and R is a quadratic regularization function such that (13) for a nonnegative definite matrix .…”
