	Note that this must be performed before waterproofing of the outer surface of the skull. In other words, for this phantom the skull compartment is waterproofed in two steps. First, the inside of the front and back halves and the mating grooves are sprayed with waterproof rubber spray. The two halves are then glued together with epoxy. Second, the holes are covered as described above. Finally, the outer surface of the skull (including seran wrap covering the holes) is waterproofed using the rubber spray.

 This phantom was created based on the automatic segmentation of a human subject. Surfaces were created using the marching cube algorithm ("isosurface" function in Matlab) and were simplified using Meshlab ("Laplacian Smooth" and "Quadric Edge Collapse Decimation" functions).
