Homogeneous Head-Size Sphere Phantom Model

The sphere has a relative permittivity of 41.5 and conductivity of 0.97 S/m which are the IEEE standard SAM head phantom values at 900 MHz [10]. The sphere has a radius of 0.104 m. A voxel and a tetrahedral CAD model are available for download. The voxel model was created from a set of images that contained slices of a sphere with a pixel resolution of 1/3 × 1/3 mm² in the x-y plane and 1 mm resolution between slices in the z-direction, i.e., the same resolution as the Visible Human Male dataset that was used to construct the AustinMan model. These slices were then coarsened and extruded (using the 3-D coarsening method) in the same manner as the AustinMan model to produce the voxel model. The CAD model was generated using NX I-DEAS.

The homogeneous sphere models were used in [14-20] and are available for validation purposes. The homogeneous sphere models were added to the AustinMan website on 8/5/2011.
