Achtergrond: Dansers zijn atletische kunstenaars werkzaam binnen een gewichtsklassesport. Om te voldoen aan de juiste ranke lichaamssamenstelling zijn dansers geneigd extreme methodes in te zetten. Om complicaties als gevolg hiervan te voorkomen is het meten en monitoren van de lichaamssamenstelling …

Het Mauritshuis doet momenteel onderzoek naar de pigmenten en laagopbouw in verfmonsters uit kunst van Jan Steen en Giovanni Antonio Pellegrini. Hierbij wordt met Shell Nederland BV samengewerkt onder het Partners in Science project. Een onderdeel van dit project is een onderzoek naar het blauwe pigment …

In this thesis the research on the automatic constructing of intelligible digitally reconstructed radiographs (DRR’s) of the hips is described. This project was initialized when the Department of Orthopedic surgery, within UMC Utrecht, decided to research the relation between spinopelvic parameters and …

The aim for this thesis is to set up and develop electroplating technique for depositing gold layers. This gold layer will be used as an thermalisation layer in a cryogenically cooled X-ray detector. Key material parameter for the gold layer is a low thermal resistivity at cryogenic temperatures. Since …

When treating cancer by radiation therapy it is always the goal to irradiate the tumour as much as possible and to spare the healthy tissue around it. For this a new type of radiation therapy called Volumetric Modulated ARC Therapy (VMAT) has been developed. During VMAT treatment the radiation machine …

In the medical community, X-rays are an important tool in imaging the human body. In principle X-ray images are 2 dimensional images. By measuring such X-ray images at multiple angles, one can construct the 3 dimensional inner structure of the sample. This 3 dimensional structure is created by applying …

The observed persistent soft X-ray spectra (0.5 - 10 keV) of anomalous Xray pulsars (AXPs) can be explained by the magnetar model (Woods and Thompson et al., 2002 [3]) where the emission is powered by the decay of an extreme high magnetic eld ( 1014 G). Because these spectra are relatively soft, measurements …
