Reconstruction of high resolution MLC leaf positions using a low resolution detector for accurate 3D dose reconstruction in IMRT

Visser, R.; Godart, J.; Wauben, D.J.L.; Langendijk, J.A.; van 't Veld, A.A.; Korevaar, E.W.

In pre-treatment dose verification, low resolution detector systems are unable to identify shifts of individual leafs of high resolution multi leaf collimator (MLC) systems from detected changes in the dose deposition. The goal of this study was to introduce an alternative approach (the shutter technique) …

Efficient and reliable 3D dose quality assurance for IMRT by combining independent dose calculations with measurements

Visser, Ruurd; Wauben, D.J.L.; de Groot, Martijn; Godart, Jeremy; Langendijk, Johannes A.; van't Veld, A.A.; Korevaar, Erik W.

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 …
