a b s t r a c t: Objective: To study the impact of target volume changes in brain metastases during fractionated stereotactic radiosurgery (fSRS) and identify patients that benefit from MRI guidance. Material and methods: For 15 patients (18 lesions) receiving fSRS only (fSRSonly) and 19 patients (20 …

In dit praktijkgericht onderzoek wordt onderzocht in hoeverre non-coplanaire VMAT SRS als aanvulling op coplanaire VMAT SRS de treatment planning kwaliteit in de behandeling van enkelvoudige hersenmetastasen verbetert en of deze verbetering opweegt tegen een door rotaties van de bestralingstafel veroorzaakte …

Purpose/objective: Stereotactic radiosurgery of brain metastases requires highly conformal dose distributions. Besides beams setup, characteristics of the linear accelerator collimator may also play a role. In this study we compared the impact of leaf width on the dose outside the target for stereotactic …
