2D and 3D finite element meshes for modeling and optical property reconstruction. Mesh used for calculation of (a) and (d) fluence rate Φ distribution; (b) and (e) Jacobian sensitivity matrix; (c) and (f) coarser reconstruction meshes. The meshes generated in the forward calculation meshes (a),(b),(d) and (e) are finer near the source/detector positions, and grow larger toward the edge of region of interest.
