The impact of anatomical changes during photon or proton based radiation treatment on tumor dose in glioblastoma dose escalation trials
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...
The impact of anatomical changes during photon or proton based radiation treatment on tumor dose in glioblastoma dose escalation trialsCharacterization of automatic treatment planning approaches in radiotherapy
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:...
Characterization of automatic treatment planning approaches in radiotherapyErvaringen in bijdrage aan de VERT- Webinar serie voor Medisch Beeldvormings- en Bestralingsdeskundigen in opleiding in tijden van COVID-19-19
Op 16 maart sloten alle opleiding in het Hoger Onderwijs hun deuren in verband met de maatregelen als gevolg van de COVID-19 pandemie. Dit was ook het geval voor de opleiding Medische Beeldvormende en Radiotherapeutische Technieken (MBRT) van de Hogeschool Inholland in Haarlem. Deze...
Ervaringen in bijdrage aan de VERT- Webinar serie voor Medisch Beeldvormings- en Bestralingsdeskundigen in opleiding in tijden van COVID-19-19Radiation dose to the masseter and medial pterygoid muscle in relation to trismus after chemoradiotherapy for advanced head and neck cancer
Abstract Background: We studied the relationship between trismus (maximum interincisor opening [MIO] ≤35 mm) and the dose to the ipsilateral masseter muscle (iMM) and ipsilateral medial pterygoid muscle (iMPM). Methods: Pretreatment and post-treatment measurement of MIO at 13 weeks...
Radiation dose to the masseter and medial pterygoid muscle in relation to trismus after chemoradiotherapy for advanced head and neck cancerPredicting and implications of target volume changes of brain metastases during fractionated stereotactic radiosurgery
a b s t r a c t: Objective: To study the impact of target volume changes in brain metastases during fractionated stereotactic radiosurgery (fSRS) and identify patients that benefit from MRI guidance. Material and methods: For 15 patients (18 lesions) receiving fSRS only (fSRSonly)...
Predicting and implications of target volume changes of brain metastases during fractionated stereotactic radiosurgeryTreatment planning of stereotactic radiosurgery for single brain metastases: impact of leaf width
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...
Treatment planning of stereotactic radiosurgery for single brain metastases: impact of leaf widthDose to the masseter muscle and risk of trismus after chemoradiation for advanced head & neck cancer
Purpose / objective: Head and neck cancer patients treated with chemoradiation are at risk for developing trismus (reduced mouth opening). Trismus is often a persisting side-effect and difficult to manage. It impairs eating, speech and oral hygiene, affecting quality of life....
Dose to the masseter muscle and risk of trismus after chemoradiation for advanced head & neck cancerGebruik van PET-CT en MRI bij de radiotherapeutische behandeling van gynaecologische maligniteiten
Het doel van het onderzoek is om te bepalen welke voordelen de fusie van PET-CT en MRI-CT hebben in het voorbereidingstraject van de behandeling van de gynaecologische patiënt met radiotherapie ten opzichte van CT alleen. Hierbij is gekeken naar voordelen met betrekking tot...
