Purpose/Objective: Most dose-escalation trials in glioblastoma patients integrate the escalated dose throughout the standard course by targeting a specific subvolume. We hypothesize that anatomical changes during irradiation may affect the dose coverage of this subvolume for both proton- and photon-based …

Introduction: The Netherlands does not have a national guideline for performing radiographic exami nations on pregnant patients. Radiographic examination is a generic term for all examinations performed using ionizing radiation, including but not limited to radiographs, fluoroscopy and computed tomogra …

Background and purpose: Automatic approaches are widely implemented to automate dose optimization in radiotherapy treatment planning. This study systematically investigates how to configure automatic planning in order to create the best possible plans. Materials and methods: Automatic plans were generated …

Introduction: In clinical practice AP pelvis standard protocols are suitable for average size patients. However, as the average body size has increased over the past decades, radiographers have had to improve their practice in order to ensure that adequate image quality with minimal radiation dose to …

INTRODUCTION: With the introduction of digital radiography, the feedback between image quality and over-exposure has been partly lost which in some cases has led to a steady increase in dose. Over the years the introduction of exposure index (EI) has been used to resolve this phenomenon referred to as …

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 …

Door recente verlaging van de equivalente dosis van de ooglens van 150 mSv naar 20 mSv per jaar, is het belang van goed monitoren van ontvangen dosis nog belangrijker geworden. In deze studie is onderzocht wat de stralenbelasting is van interventiecardiologen, cardio-thoracaalchirurg, cardio-anesthesiologen …

Het doel van dit onderzoek is om te identificeren welke factoren invloed hebben op het gewichtsverlies tijdens de chemoradiatie van patiënten met NSCLC-stadium III. Door deze factoren te bepalen, kan hier mogelijk preventief op worden ingespeeld tijdens het behandelproces. Van de NSCLC-stadium III patiënten …

Op de angiografie worden interventies van de bloedvaten uitgevoerd, waarbij de medewerkers worden blootgesteld aan straling. In de recente wetgeving is de dosis voor de ooglens bijgesteld van 150 mSv naar 20 mSv per jaar. In deze studie is onderzocht wat de ontvangen ooglensdosis van de interventie radiologen …
