Alongside a clinical and research setting, whole body magnetic resonance imaging (WB-MRI) is increasingly offered as a direct-to-consumer screening service. Data is needed on the clinical relevance of findings and associated psychological impact of such screening. Therefore, we conducted a prospective follow-up study to provide...article 2020

(author), TNO Industrie en Techniek (author)Feasibility of pulse oxigraphy is examined using an in- vitro phantom, perfused with human blood by a heart- lung machine. 29 different oxygen saturation levels, measured with our experimental camera and a clinical pulse oximeter, were matched against laboratory blood gas analysis. Discrete transfer functions between measurements & laboratory...conference paper 2007

Wieringa, F.P. (author), Mastik, F. (author), van der Steen, A.F.W. (author), TNO Kwaliteit van Leven (author)We describe a route toward contactless imaging of arterial oxygen saturation (SpO2) distribution within tissue, based upon detection of a two-dimensional matrix of spatially resolved optical plethysmographic signals at different wavelengths. As a first step toward SpO 2-imaging we built a monochrome CMOS-camera with apochromatic lens and 3λ-LED...article 2005

(author), TNO Kwaliteit van Leven (author)The introduction of drug-eluting stents (DES) to prevent in-stent restenosis is one of the major advances in interventional cardiology. Currently many types of DES are under evaluation for effectiveness and safety, a time-consuming and difficult procedure in humans. An animal model that allows rapid evaluation of the present and upcoming...article 2005
