Incorporating in-room MR
• Many sites soft tissue contrast not optimal with CT
• Interest in MR
• High soft tissue contrast • Imaging could be repeated during XRT • Functional imaging/early response assessment
• Challenges
• Primary photon beam not affected by field but secondary electrons experience Lorentz force • Field also affects dose response of ionisation chambers • Geometric accuracy would need to be sub-mm
