The objective of this study was to introduce a new iterative method to reconstruct multi leaf collimator (MLC) positions based on low resolution ionization detector array measurements and to evaluate its error detection performance. The iterative reconstruction method consists of a fluence model, a detector …

In deze openbare les presenteert Linda Wauben, Lector Technische Innovatie in de Zorg, de Zorgtechnologie-aanpak (de ZoT aanpak). De ZoT aanpak wordt toegepast in onderzoeks- en onderwijsprojecten en wordt uitgevoerd in nauwe samenwerking met de eindgebruikers (onder anderen cliënten, formele zorgprofessionals …

Background and purpose: Treatment plan verification of intensity modulated radiotherapy (IMRT) is generally performed with the gamma index (GI) evaluation method, which is difficult to extrapolate to clinical implications. Incorporating Dose Volume Histogram (DVH) information can compensate for this. …

PURPOSE: Advanced radiotherapy treatments require appropriate quality assurance (QA) to verify 3D dose distributions. Moreover, increase in patient numbers demand efficient QA-methods. In this study, a time efficient method that combines model-based QA and measurement-based QA was developed; i.e., the …
