Magnetic decoupling of the linac in a low field biplanar linac-MR system

  title={Magnetic decoupling of the linac in a low field biplanar linac-MR system},
  author={James St. Aubin},
Purpose: The integration of a low field biplanar magnetic resonance MR imager and linear accelerator linac causes magnetic interference at the linac due to the MR fringe fields. In order to eliminate this interference, passive and active magnetic shielding designs are investigated. Methods: The optimized design of passive magnetic shielding was performed using the finite element method. The design was required to achieve no greater than a 20% electron beam loss within the linac waveguide and… CONTINUE READING
