After our paper [1] was published, an existence of a related patent [2] came to notice and it should have been mentioned, as should the use of a similar format for Fig. 1 to Fig. 4 in Ref. [3] (Ref. [17] in our original paper [1]). The corrected figure caption of Fig. 1 is as follow.

 

Fig. 1. (a) The organ probability map estimated from the statistical shape model without a body-conforming animal mold. The probability distribution of (b) the liver, (c) the right kidney and (d) the soft tissue. The figure referred to the organ probability map introduced in Fig. 4 from Ref. [3] and patent [2].

The organ probability map was completely different. The organ probability map in Ref. [2] and [3] was from a body-conforming animal mold and all 9 organs are in the form of probability map. However, the organ probability map in our work was established directly from our statistical mouse atlas which does not need an animal mold. Meanwhile, the lung and skeleton are fixed organs, and only the heart, liver, kidney and soft tissue are in the form of probability map in our work.

The work focuses on the feasibility of a two-step BLT reconstruction method in conjunction with an organ probability map obtained without any body-conforming animal mold to accurately reconstruct the localization of the bioluminescent light source. It goes well beyond the earlier paper and thus the conclusions remain.
