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 …

In this contribution the current status and future development of four Global Navigation Satellite Systems (GNSS) are reviewed. They are the American Global Positioning System (GPS), the Russian Glonass, the European Galileo and the Chinese BeiDou Compass. All four systems offer, or will offer, civil …

This study explores the capability of the COMPASS system (IBA Dosimetry, Germany) to detect leaf positioning errors of a high resolution MLC with 4mm leaf width using a lower resolution (7.62mm detector spacing) 2D matrix of ionisation chambers

A recent employees satisfaction audit, showed that the employees of Eurest in Holland Casino Utrecht were very dissatisfied about 'communication'. Though, when I asked them they could not describe the exact problem and if I would ask what needed to change for them in order to improve the communication …

Het thema 'waardeneducatie' staat bij veel instellingen van hoger (beroeps)onderwijs hoog op de agenda. De laatste jaren groeit het besef, dat studenten opgeleid moeten worden tot 'reflective practitioners', dat wil zeggen professionals die zich niet alleen op het terrein van kennis en vaardigheden hebben …
