Needle-free Biopsy of the Esophagus: Quantitative Magnetic Resonance Imaging as Alternative to Endoscopic Diagnosis
In this project Sebastian Weingärtner, Hildo J. Lamb and Frans Vos develop new tools to diagnose a form of coronary artery disease that is not caused by obstruction in the major vessels. This form accounts for the majority of coronary artery disease cases in women but is rarely seen in man. Thus, conventional clinical methods often miss the diffuse pathological changes seen in this syndrome.

Paul Urbach and Zheng Xi published paper on resolution with far field optics in Photonics Magazine
It is common knowledge in optics that, when only tar fields are measured, there is a fundamental limit to the resolution given by the wavelength of the light. Yet research continues to beat this fundamental limit.

Pieter Kruit et al published paper on "Reducing the Magnetic Fields around DC Light Rail Systems"
DC electrified light rail or tram systems cause low frequency magnetic fields that may disturb scientific and medical instruments in their environment. A concept was developed that significantly reduces these magnetic fields.

Leon van der Graaff and Sjoerd Stallinga have published a paper on Computational imaging modalities for multi-focal whole-slide imaging systems in Applied Optics
This research was carried out in cooperation with pathologists from Erasmus MC and Leiden University MC, and reports on new ways to image tissues in 3D, using a slide scanner that can scan multiple focal layers in a single scan. The images were acquired on a research prototype of such a scanner of Philips Digital & Computational Pathology.

Eerste detector-array gereed voor GUSTO ballonmissie
De eerste detector-array voor NASA's GUSTO-missie heeft zijn pre-shipment review doorstaan en wordt nu naar de Universiteit van Arizona verzonden voor integratie in de ballontelescoop. SRON ontwikkelt samen met TU Delft de drie 8-pixel-arrays, voor de frequenties 4.7, 1.9 en 1.4 terahertz. Ze hebben nu de array voltooid voor het 4.7 terahertzkanaal—het lastigste onderdeel. GUSTO is een ballonmissie die de emissies gaat meten van materiaal tussen de sterren; het interstellaire medium.

Paper Martijn Nagtegaal on "Myelin water imaging from multi-echo MR relaxometry data using a joint sparsity constraint" is published in NeuroImage
Myelination is a crucial aspect of brain development and is essential for the functioning of the nervous system. Demyelination, on the other hand, is a pathological process that plays an important role in certain diseases such as multiple sclerosis. Accurate measurement of myelin content has the potential to increase our insights into several disease processes. Magnetic resonance imaging (MRI) enables imaging of features related to (de-)myelination in vivo. Martijn Nagtegaal uses dictionary matching and a joint sparsity multicomponent T2 fit to obtain MWF maps.
