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 …

Abstract: Since the first Oxford Survey of Childhood Cancer’s results were published, people have become more aware of the risks associated with prenatal exposure from diagnostic x rays. As a result, it has since been the subject of many studies. In this review, the results of recent epidemiological …

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 …

Abstract Background: The benefit of MR-only workflow compared to current CT-based workflow for prostate radiotherapy is reduction of systematic errors in the radiotherapy chain by 2–3 mm. Nowadays, MRI is used for target delineation while CT is needed for position verification. In MR-only workflows, …

Spierechografie wordt op dit moment niet optimaal benut in ziekenhuizen. Dit komt mede doordat er veel ervaring nodig is om spierechografiebeelden te beoordelen. Om minder ervaren beoordelaars in de toekomst te helpen wordt er in dit onderzoek een nieuw visueel scoresysteem getest. Uit dit onderzoek …

De gouden standaard bij de diagnose COVID19 is de RT-PCR test. De accuratesse van die test kan echter in twijfel worden getrokken. Doel van het onderzoek is het bepalen van de waarde van de CT-thorax bij de diagnose COVID19. Bij de beoordeling van CT-thorax worden CORADS en CTSS gebruikt. De gevonden …

In face of climate change and urbanization, the need for thermally comfortable outdoor urban spaces is increasing. In the design of the thermally comfortable urban spaces and decision making about interventions that enhance thermal comfort, scientists and professionals that work for cities use meteorological …

Cone beam CT scanners use much less radiation than to normal CT scans. However, compared to normal CT scans the images are noisy, showing several artifacts. The UNet Convolutional Neural Network may provide a way to reconstruct the a CT image from cone beam scans.

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 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 …
