Optimization of a fast optical CT scanner for nPAG gel dosimetry
2009
Journal of Physics, Conference Series
A fast laser scanning optical CT scanner was constructed and optimized at the Ghent university. The first images acquired were contaminated with several imaging artifacts. The origins of the artifacts were investigated. Performance characteristics of different components were measured such as the laser spot size, light attenuation by the lenses and the dynamic range of the photo-detector. The need for a differential measurement using a second photodetector was investigated. Post processing
