Mutic, Sasa ; Zhang, Tiezhi
T-016307

— Technology Description This technology is a patented LINAC (linear accelerator) radiation therapy system designed to enable non-coplanar cone beams to be delivered from all angles by using a ring gantry instead of a robotic moving couch. This simple approach enables easier treatment planning and q…

Tetrahedron Beam Computed Tomography with Multi-pixel X-ray Source
Zhang, Tiezhi
