Analysis of radiation exposure data from common radiological procedures in Dutch hospitals

Bijwaard, H; de Vries, G; de Waard-Schalkx, I; van Welie, F; Haarmans-Jonkman, Sharon; Erenstein, H (Healthy Ageing, Allied Health Care And Nursing); Scheurleer, J; Roding, T; Middendorp, I V; van der Ploeg, T

INTRODUCTION: In the Netherlands, Diagnostic Reference Levels (DRLs) have not been based on a national survey as proposed by ICRP. Instead, local exposure data, expert judgment and the international scientific literature were used as sources. This study investigated whether the current DRLs are reasonable …

Multivariable normal tissue complication probability model-based treatment plan optimization for grade 2-4 dysphagia and tube feeding dependence in head and neck radiotherapy

Kierkels, Roel G J; Wopken, Kim; Visser, Ruurd; Korevaar, Erik W; van der Schaaf, Arjen; Bijl, Hendrik P; Langendijk, Johannes A

BACKGROUND AND PURPOSE: Radiotherapy of the head and neck is challenged by the relatively large number of organs-at-risk close to the tumor. Biologically-oriented objective functions (OF) could optimally distribute the dose among the organs-at-risk. We aimed to explore OFs based on multivariable normal …

Treatment planning of stereotactic radiosurgery for single brain metastases: impact of leaf width

Emmy Lamers (Lid Lectoraat)

Purpose/objective: Stereotactic radiosurgery of brain metastases requires highly conformal dose distributions. Besides beams setup, characteristics of the linear accelerator collimator may also play a role. In this study we compared the impact of leaf width on the dose outside the target for stereotactic …

Evaluation of DVH-based treatment plan verification in addition to gamma passing rates for head and neck IMRT

Visser, Ruurd; Wauben, David J.L.; de Groot, Martijn; Steenbakkers, Roel J.H.M.; Godart, Jeremy; van 't Veld, Aart A.; Langendijk, Johannes A.; Korevaar, Erik W.; Bijl, Hendrik P

Background and purpose: Treatment plan verification of intensity modulated radiotherapy (IMRT) is generally performed with the gamma index (GI) evaluation method, which is difficult to extrapolate to clinical implications. Incorporating Dose Volume Histogram (DVH) information can compensate for this. …

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 …

Determination of total uncertainty in dose of the radiochromic film dosimetry method

L. Martijn (Student); M.C. Vloemans (Begeleider)

The treatment of tumours in cancer patients have become more advanced and thus more complex. The verification of the dose distribution, calculated by clinical physicists, have thus become more complicated. VSL has started the development on measurements of absolute dose distributions in an antrhopomorphic …
