SBO (SFUD) and MBO (IMPT)
SBO: Single beam optimization
– Possible with passive scattering and active scanning technology
– Spots are weighted in order to achieve a homogenous target dose for
every single beam
– OAR sparing only possible by using help structures
– More robust treatment plans
MBO: Multi Beam Optimization
– Active scanning required
– Single beam target doses are not homogenous
– Better OAR sparing possible
