Silicon detectors produced from materials with different doping and oxygen concentration have been irradiated with 27 MeV and 23 GeV protons, 192 MeV pions and 5.3 MeV neutrons. In isothermal annealing studies at 60°C the microscopic defect evolution (measured with DLTS) and the changes in the detector leakage current were monitored in parallel. It is shown(More)
PURPOSE Diffusion-weighted imaging (DWI) has become an important component in modern stroke imaging. This MR technique detects diffusion abnormalities, which can be quantified by computing apparent diffusion coefficient (ADC) maps. ADC values are typically calculated from a set of MR images obtained with varying degrees of diffusion weighting (b-values)(More)
