Conclusions
• Prior diagnostic MRI (Axial T2 TSE + DWI)
• Understand limitations of ‘cognitive fusion’ or rigid
registration
• Consider GTV in treatment planning
• Minimize motion between imaging and delivery
• Patient imaging and transfer on tabletop in frog-leg
• Imaging protocol - mitigates geometric uncertainties
– TSE, high BW, high signal, high res, remove metal,
balance device and anatomic resolution
