ATP Barcelona 2017

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
