Gesellschaft für Forschungs- und Entwicklungsservice mbH
GF&E delivers physical-technical R&D-services. Our goal ist to apply and transfer key-technologies – especially from GSI developed methods, techniques and qualifications.

Positron Emission Tomography
• Uses 18F (β+-Emitter, λ=110 minutes)
• 18F is attached to tracer (Glucose)
• Glucose is enriched in body parts with high energy intake
• Tumors need much energy to grow fast

Summary
• No redundance of application sourcecode for simulation
• Easy adaption of scenarios through text files
• Use of ROOT for presentation of analysis results
