Advanced Brachytherapy Physics - Vienna 2016

Seed/Applicator Model Accuracy Requirements • Patient CT grids (>1 mm voxel) are probably not adequate for accurate modeling on the spatial scale of brachytherapy sources and applicators. • MBDCA vendors should use analytic modeling schemes or recursively specify meshes with 1 10 μ m spatial – resolution. • Vendors to disclose their geometry, material assignments, d f t i t l t b th d d TPS an manu ac ur ng o erances o o en users an vendors (if responsible for data entry and maintenance)
