Summary 1 - Pencil Beam Scanning
•
Pencil Beam Scanning (PBS) exploits the charge to
magnetically scan particle pencil beams across the
target.
•
Dose is confined to the target by actively steering
the individual particle pencil beams such that only
Bragg peaks that stop in the target volume are
delivered.
•
‘Scanning’ of beam is performed in depth through
the use of Bragg peak specific energy modulation
•
No field specific hardware
(collimators/compensators) required
