US Patent 9018603 Pluridirectional very high electron energy radiation therapy systems and processes

A compact high-gradient, very high energy electron (VHEE) accelerator and delivery system (and related processes) capable of treating patients from multiple beam directions with great speed, using all-electromagnetic or radiofrequency deflection steering is provided, that can deliver an entire dose or fraction of high-dose radiation therapy sufficiently fast to freeze physiologic motion, yet with a better degree of dose conformity or sculpting than conventional photon therapy. In addition to the unique physical advantages of extremely rapid radiation delivery, there may also be radiobiological advantages in terms of greater tumor or other target control efficacy for the same physical radiation dose.
