Homogeneous Model
During the development of the AustinMan Electromagnetic Voxels, a homogeneous whole-body and a partial-body (head and shoulders) voxel model were also developed by using the mask slices 1001 - 2878 and 1001 - 1354, respectively (Fig. 3). Various resolution models (from 1/3 × 1/3 × 1 mm3 to 16 × 16 × 1 mm3 ) were obtained: Homogeneous AustinMan v1.0 and Homogeneous AustinMan v1.1 models were obtained using the 2-D coarsening and 3-D coarsening methods, respectively. All the voxels in the models are assigned the following electromagnetic properties: Relative permittivity εr = 55.0 and conductivity σ = 1.05 S/m for whole-body models and εr = 41.5 and conductivity σ = 0.97 S/m for partial-body models; these are the IEEE standard SAM phantom values at 900 MHz [11]. Note again the caveat that the homogeneous AustinMan voxel models are slightly larger than the actual body (see the Masking section).
Due to the inherent inaccuracy of representing the entire human body with a single effective material, these models are not posted online. Users are strongly encouraged to use the heterogeneous models. Please contact us to discuss obtaining the homogeneous models.
