Abstract

A radiation system includes a radiation source having an accelerator, the radiation source having a magnetic field associated therewith that is resulted from an operation of the accelerator, and a magnetic field source configured to provide a compensating magnetic field to at least partially counteract against the magnetic field that is resulted from the operation of the accelerator. A radiation system includes a radiation device having a radiation source, a patient support, and a protective guard located between the radiation source and the patient support, wherein the protective guard is moveably coupled to the radiation device or the patient support. A radiation system includes a particle generator for generating a particle, an accelerator for accelerating the particle, and a magnetic source for changing a trajectory of the particle, wherein the magnetic source comprises a permanent magnet.

First claim

1 - 64 . (canceled)

65 . A radiation system, comprising:
a structure having a first side, a second side, a first opening located on the first side, and a patient-accommodating space that extends from the first opening; a radiation source coupled to the structure; and a patient support configured to position a part of a patient from a first operative position that is associated with the radiation source to a second operative position that is outside the bore, or vice versa, the first operative position being in the bore; wherein the first operative position comprises a treatment space aimed at by the radiation source, and wherein the second operative position comprises an imaging space.
