Forschungsgebiete
-
- Marcel beschäftigt sich mit der Entwicklung von Niederfeld-MRT-Systemen, wobei der Schwerpunkt auf der Entwicklung modularer Auslese-Hardwaresysteme liegt. Der Fokus liegt dabei insbesondere auf der Echtzeitsynchronisierung von eingebetteten Systemen und Field Programmable Gate Arrays (FPGA), um komplexe Signalverarbeitungsalgorithmen in Echtzeit zu implementieren. Durch die Optimierung von Software- und Hardwaresystemen wird eine präzise Synchronisation der erfassten Daten sichergestellt, was die Effizienz der Datenanalyse für bildgebenden Verfahren signifikant verbessert.
