SU-E-T-12: Radiation Detector Responses to Applied Homogeneous Transverse and Parallel Magnetic Fields.

This work has significant impact on dosimetry protocols for integrated MR-linac systems, where detector response may be altered by the presence of a magnetic field. The need for a magnetic field dependent correction factor is strongly indicated for the transverse magnetic field cases, while such changes in detector response can be largely ignored in parallel magnetic fields < 1T.
