Proton rescanning: which works best?  

From medicalphysicsweb.org, 28 November 2013

Particle timgherapy is an increasingly popular cancer treatment, with active spot scanning the delivery method of choice for most new facilities. Treating mobile targets with spot scanning, however, is limited by interplay effects between tumour and beam motion, which lead to target dose inhomogeneities. One way to mitigate such effects is to use rescanning – either volumetric scanning, where dose is delivered across a series of full-volume rescans, or layered rescanning, which delivers all scans in one energy plane before moving to the next.

To compare the two schemes, researchers from ETH Zurich and the Paul Scherrer Institute (PSI) in Switzerland have performed a detailed simulation study modelling the interplay effects for a range of system and beam delivery scenarios. Read more >>
