| Three dimensional radiation therapy is a radiation therapy technique where the dose is calculated with projection onto 3D imaging (e.g., CT or MRI) delivered with either static aperture (collimator, stereotactic radiosurgery cone, static multi-leaf collimators, blocks, etc) or non-intensity modulated radiation therapy/volumetric modulated arc therapy dynamic apertures (e.g., field-in-field, dynamic arc) using either single gantry angles or arcs. |
