Voxel-Based Body Modification Software which Preserves Internal Organs and Structures

The interaction of radio frequency electromagnetic energy with the human body is best computed with finite difference methods. For good accuracy, especially at higher frequencies, the human body description requires many millions of individual voxels. Thevoxels fill the entire volume of the body and describe both the outer surface and interior organs of the body. Making one detailed voxel mesh of the human body is a significant project that may take years of effort. The result will be a voxel mesh foronly one position of the body. However, different applications require the body limbs to be repositioned. The body might be seated, keeling, standing, or holding a cellular phone. Modifying the voxel mesh of the body to the new positions whilemaintaining the integrity of the internal organs is a difficult task, beyond the capabilities of currently-available computer aided design software. During the Phase I effort an approach to this problem was demonstrated by rotating the 1mm voxel anklejoint and demonstrating continuity of the rotated nerves and blood vessels. In this effort the complete ability to manipulate large three-dimensional voxel-based meshes, primarily of the human body, while maintaining the fidelity of the mesh, will bedeveloped.
