Rationale for IGPT
• Particle therapy is lacking proper IGRT (mostly orth. X-rays)
– this is not sufficient !
• Only some recent facilities have X-ray CBCT
– probably not sufficient ?
• Proton RT is clearly indicated for pediatric patients
– can we justify the additional imaging dose ?
IGPT is more important than IGRT !
CT on rails at PSI, Dresden, Trento; Novel DECT system at MedAustron; Robotic C-arm at HIT
Why not go straight to MRgPT ?

How about a real hybrid system?
Hybrid MRI proton system
, patent by J.
Overweg 20110230754, Philips, Germany, 2012.
Bunker layout at Ingham Inst., Sydney
Including an MRI in a proton gantry is technically non-trivial
Current designs look at
fixed beam-lines
Not very convincing…
