Title:	Dosimetric consequences of respiratory motion for a scanned proton beam Investigation of motion mitigation techniques for scanned proton beam irradiation of a moving lung tumour
Abstract ( 300 words ):	The influences of interplay effects on the dose distribution caused by the interference of the moving beam with the moving tumour are of major concern in the advancement of particle therapy. For the treatment of moving tumours with scanned particle beams, motion mitigation techniques are mandatory. Furthermore, as rapid progress in the development of new particle accelerators and delivery devices is made, tools to predict the delivered dose on a patient specific basis are essential for their application in patient treatment. A computer based tool has been developed which simulates the delivery of a scanned proton beam to a moving lung tumour. In this work we evaluate the influence of rescanning on the dose distribution with particular regard to fast energy variation. Additionally, the dosimetric effect of gating has been investigated.
