🎯 3D Radiotherapy Dose Calculation — Volumetric TPS Engine

A genuine 3D voxel dose engine: CT-derived tissue density fills a spherical patient volume, a rotating VMAT gantry arc ray-traces beams through it with Beer-Lambert attenuation, and a 3D diffusion kernel converts released energy into an absorbed dose cloud you can orbit, zoom, and filter by isodose threshold.
