In this thesis the workings of a time-resolved setup are treated as well as the underlying physics. The setup is based on optical gating, which gives control over very short moments in time to let light pass through a gate. As this process is stable, light can be studied in very short and low intensities. …

De klanten van Tata Steel stellen steeds hogere eisen aan het productenpakket dat zij afnemen. Het product moet voldoen aan de productspecificaties en moet van zeer consistente kwaliteit zijn. Poeder dat gebruikt wordt om het continu gietproces mogelijk te maken, kan in de vloeibare toestand opgesloten …

Abstract: Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. …

Onderzoek naar de relatie elektrische geleidbaarheid, gemeten door de verisscan, en het percentage lutum van de bodem.

Three-dimensional (3D) body scanning becomes increasingly important in the medical, ergonomical and apparel industry. The SizeStream 3D body scanner is a 3D body scanner in the shape of a fitting room that can generate a 3D copy of the human body in a few seconds. The Poikos modeling system generates …

Scanning tunneling microscopy is an important and enabling tool for condensed matter physics and surface science. The low temperature STM in Leiden (Prof. J. Van Ruitenbeek and Prof J. Aarts) is used for research in the field of atomic/molecular electronics and superconductivity. The current low temperature …

Background: Endothelial dysfunction is a marker of early stages of atherosclerosis and in general of cardiovascular disease. Assessing the endothelium can be achieved non-invasively, using the flow-mediated dilatation technique. Method: For the experiment 21 patients with an inactive cardiovascular …

Optical Coherence Tomography (OCT) is an imaging technique for collecting depth resolved information in human tissue based on an interferometer. With an imaging depth of between 1 and 2 mm, OCT is only used to investigate (near) surfaces. But with an axial (depth) resolution of between 2 and 10 μm, and …

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 …

Full text via link. This study compares the reliability and reproducibility of flow-mediated dilatation (FMD) and peripheral arterial tonometry (PAT) to assess endothelial function. Eighteen volunteers with coronary heart disease underwent simultaneous testing of FMD by means of brachial artery ultrasound …
