To quantify the dosimetric accuracy of the COMPASS correction kernel method, and to determine its ability to detect dose delivery errors caused by MLC leaf mis-positioning.

The main objective of this study was to make the transition from a film (2D) based pre-treatment IMRT / IMAT QA into a more efficient and clinical relevant method of verification by reconstructing the dose directly in the patient CT using the COMPASS system. The evaluation of the reconstructed dose includes …

Functieverandering is een instrument om de landschappelijke kwaliteit te verbeteren door vrijkomende agrarische bebouwing te verwijderen uit het landelijk gebied. In ruil hiervoor wordt aan initiatiefnemers de mogelijkheid geboden om gebouwen te hergebruiken als woning en/of nieuwe wooneenheden te realiseren. …

Professional development needs to be understood as a spontaneous process of learning at work before moving on toward the 'desired' professional development. Learning as a result of working is often implicit, stems from social interaction and direct experience, involves the (thoughtless, implicit) reproduction …

Abstract—In many biomechanical motion studies, kinematic parameters are estimated from position measurements on a number of landmarks. In the present investigation, dummy motion experiments are performed in order to study the error dependence of kinematic parameters on geometric factors (number of markers, …

In biomechanical joint-motion analyses, the continuous motion to be studied is often approximated by a sequence of finite displacements, and the Finite Helical Axis(FHA) or "screw axis" for each displacement is estimated from position measurements on a number of anatomical or artificial landmarks. When …
