Notwithstanding its great success in diagnostic routine and research, structural magnetic resonance imaging (MRI) still faces challenges. In this context, the present thesis studies new approaches to mitigate the motion susceptibility of MRI. Furthermore, ...
The purpose of this study was to evaluate a new polymer-based and magnetic resonance (MR) imaging-compatible guide wire for its application in MR-guided endovascular interventions, particularly for interventional peripheral MR angiography in swine experime ...
The current status of the ITER magnetics diagnostic is summarised. The various risks are discussed on the basis of when they could be present during ITER operation and appropriate mitigation is reviewed. An implementation risk or common mode operation fail ...
Interventional radiology is a minimally invasive procedure where thin instruments, guidewires and catheters or stents are steered through the patient’s vascular system under X- ray imaging for treatment of vascular diseases. The complexity of these procedu ...
Technical difficulties associated with excavation works in tectonized geological settings are frequent. They comprise instantaneous and/or delayed convergence, sudden collapse of gallery roof and/or walls, outpouring of fault-filling materials and water in ...
Common indicators used to examine the potential for utilising natural radiation of urban forms include the sky view factor (V-s), the height to width ratio and the urban horizon angle. These indicators are conveniently related to one another. In comparing ...
A real-time pulse height analysis (PHA) X-ray diagnostic for the TCV tokamak has been developed using CFN multi-DSP-based VME acquisition, processing and control board. The hardware is composed by: (i) a detection system based on a Si SDD detector; (ii) a ...
