Abstract:
1. A radiation therapy system comprising: a magnetic resonance imaging (MRI) apparatus configured to generate an MRI magnetic field, the MRI apparatus comprising at least a first magnet and a second magnet spaced apart to define a first gap there between, wherein the first magnet includes an opening therein having a central axis, and wherein the first magnet and the second magnet are co-axially aligned along the central axis so that the central axis extends from the first magnet to the second magnet; and a linear accelerator configured to generate a beam of radiation, the linear accelerator coupled to the MRI apparatus so that an axis of particle travel in an accelerating waveguide of the linear accelerator is co-axially aligned with the central axis and configured to expose particles being accelerated therein to the MRI magnetic field so that magnetic force directs the particles along the axis of particle travel.
