Angle dependence of the beam position
Naoya Saotome(NIRS) 34
Digital starshout device
3D Water phantom
The accuracy of the isocenter position and gantry angles are
checked using digital starshout device
Beam position accuracy for each gantry angle was confirmed within
+/- 0.5mm.

SUMMARY
2017/2/23 Naoya Saotome(NIRS) 40
Fast scanning system dedicated for moving target was
succeeded at NIRS
Commercial system which is combination of a compact
dissemination treatment system and pencil beam 3D
scanning technique was constructed at KCC
Treatment using superconducting rotating-gantry will be
started in near future
