Quality of life among prostate cancer patients: a prospective longitudinal population-based study

Schaake, Wouter (Healthy Ageing, Allied Health Care And Nursing); de Groot, Martijn; Krijnen, Wim (Statistical Techniques For Applied Research); Langendijk, Johannes A.; van den Bergh, Alfons C.M.

Purpose To investigate the course of quality of life (QoL) among prostate cancer patients treated with external beam radiotherapy and to compare the results with QoL of a normal age-matched reference population. Conclusion Prostate cancer patients experience a small worsening of QoL as compared with …

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 …

Reconstruction of high-resolution 3D dose from matrix measurements: error detection capability of the COMPASS correction kernel method

Godart, Jeremy; Korevaar, E.W.; Visser, Ruurd; Wauben, D.J.L.; van 't Veld, Aart A.

The COMPASS system (IBADosimetry) is a quality assurance (QA) tool which reconstructs 3D doses inside a phantom or a patient CT. The dose is predicted according to the RT plan with a correction derived from 2D measurements of a matrix detector. This correction method is necessary since a direct reconstruction …

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

Visser, Ruurd; Wauben, D.J.L.; Godart, Jeremy; van 't Veld, Aart A.; Korevaar, Erik.W.

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.

Reconstruction of high resolution 3D dose from low resolution matrix measurements

Godart, Jeremy; Korevaar, Erik.W.; Wauben, D.J.L.; Visser, Ruurd; van 't Veld, Aart A.

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.

Sequentially delivered boots plans are superior to simultaneously delivered plans in head and neck cancer when the boost volume is located further away from the parotid glands

Anke van Mourik; Emmy Lamers-Kuijper (Lid Lectoraat); Wilma Heemsbergen; Coen Rasch

Purpose: to find parameters that predict which head and neck patients benefit from a sequentially delivered boost treatment plan compared to a simultaneously deliverd plan, with the aim to spare the salivary glands.

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

Godart, Jeremy; Korevaar, Erik.W.; Wauben, D.J.L.; Visser, Ruurd; van 't Veld, Aart A.

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
