An efficient and independent 3D dose calculationtool for quality assurance of complex radiotherapy treatment plans

To validate the model-based 3D dose calculation performed by the COMPASS system, and to evaluate the use of the combination of model-based and measurement-based 3D dose determination for clinical QA purposes

Applicability of the Matrixx detector combined with the compass system to detect leaf positioning errors of an elekta beam modulator

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 chamber

COMPASS dose reconstruction in patient CT:the next step in pre-treatment verification

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 DVHs and a gamma index evaluation
