Positronen-Emissions-Tomographie (PET) ist eine funktionelle medizinische Bildgebungstechnik. Die Lichtausbeute und Zeitauflösung Szintillator basierter PET Detektoren wird von diversen optischen Prozessen begrenzt. Dazu gehört die Lichtauskopplung aus Medien mit hohem Brechungsindex sowie Sensitivitätsbegrenzungen der Photodetektoren. Diese Arbeit studiert mikro- und nano-optische Ansätze um diese Einschränkungen zu überwinden mit dem Ziel das Signal-Rausch Verhältnis sowie die Bildqualität zu verbessern. Dafür wird ein Lichtkonzentrator vorgeschlagen um die Sensitivität von Silizium Photomultipliern zu erhöhen sowie dünne Schichten photonischer Kristalle um die Lichtauskopplung aus Szintillatoren zu verbessern. Die Ansätze werden mit opt...
