Purpose: To investigate whether standard X-ray acquisition factors for orbital radiographs are suitable for the detection of ferromagnetic intra-ocular foreign bodies in patients undergoing MRI. Method: 35 observers, at varied levels of education in radiography, attending a European Dose Optimisation …

Patients scheduled for a magnetic resonance imaging (MRI) scan sometimes require screening for ferromagnetic Intra Orbital Foreign Bodies (IOFBs). To assess this, they are required to fill out a screening protocol questionnaire before their scan. If it is established that a patient is at high risk, radiographic …

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 …

Background: Haemodialysis patients have a high risk of malnutrition which is associated with increased mortality. Nocturnal haemodialysis (NHD) is associated with a significant increase in protein intake compared with conventional haemodialysis (CHD). It is unclear whether this leads to improved nutritional …

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 …

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 …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into …

In previous research a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed based on a circular covering geometry and an integrated filter for reflecting the near infrared radiation (NIR) of the greenhouse and exploiting this radiation in a solar energy system. …

In patients with extensive burns several causes may underliehypoxic respiratory failure and bilateral infiltrates on the chestX-ray in the first week afterburn: cardiogenic pulmonaryedema as a result of congestive heart failure, pneumonia and/or adult respiratory distress syndrome (ARDS). In particular, …
