Abstract—This paper develops a remeshing module to generate an accurate solution, FEM is an essential tool in solving partial
valid meshes for FEM in the application of Fluorescence Tomog- differential equations.
raphy Reconstruction (FTR), and it is constructed based on a Specifically, we have adapted a 3D tetrahedral mesh for
mouse atlas (Digimouse). To our knowledge, few of the recent
mesh models have been employed in the area of FTR. In our FEM in Fluorescence Tomography Reconstruction. There is
