(a) A 3D finite element mesh for the object used in the simulation. The mesh is a regular Delaunay tetrahedral with 2310 nodes and 12633 tetrahedrons. The object represents an idealized section of a mouse abdomen which illustrates 4 different tissue regions: adipose, bowel, kidneys, and bone. (b) A schematic of the object showing the detector set up and the coordinates.
