AG Technologie & Medizinische Physik (Prof. Klaus Schäfers)

Wir entwickeln neue bildgebende Technologien für die hochpräzise molekulare Bildgebung. Unsere Forschung konzentriert sich überwiegend auf hochauflösende, hochempfindliche PET-Bildgebungsverfahren in drei Projekten:

  • Beseitigung von Bewegungsartefakten in der PET/CT und PET/MRT über Verfahren der Bewegungsdetektion und -korrektur
  • Verbesserung der räumlichen Auflösung und Empfindlichkeit von Kleintier-PET durch Nutzung der Vieldraht-Proportional-Kammer-Technologie
  • Entwicklung neuer Detektoren für verbesserte time-of-flight-PET mittels Flüssig-TMBi und Cherenkov-Lichtauslesung

    MR/PET motion correction from coil fingerprints

    Dieses Projekt widmet sich der Entwicklung, klinischen Implementierung und Evaluierung einer neuartigen, Echtzeit-Bewegungskorrektur für gleichzeitige MR/PET-Akquisitionen. Verfügbare Methoden zur Datenerfassung und Rekonstruktion in MR/PET-Scannern nutzen die simultanen Bildgebungsfähigkeiten der kommerziell verfügbaren MR/PET-Geräte nicht vollständig aus.
    Diese Fähigkeiten könnten genutzt werden, um Echtzeit
    Bewegungsartefakte aus den PET-Bildern zu entfernen, ohne den Arbeitsablauf der entsprechenden MRT-Untersuchung wesentlich zu beeinflussen. Die vorgeschlagene Methode wird zu einer verbesserten Sensitivität und quantitativen Genauigkeit der PET führen, wenn diese gleichzeitig während einer MR/PET-Untersuchung erfasst werden. Solche Verbesserungen werden zu einer besseren Erkennung, Stadieneinteilung und Überwachung von kleinen (<1cm) abdominalen Läsionen, deren Beurteilung derzeit aufgrund von Signalverlust durch Bewegungsunschärfe limitiert ist.

    Targeting immune cell dynamics by longitudinal wholebody imaging and mathematical modelling

    The aim of this project is to develop strategies for tracking and quantifying (immune) cell populations or even single cells in long-term (days) whole-body PET studies in mice and humans. This will be achieved through novel acquisition protocols, measured and simulated phantom data, use of prior information from MRI and microscopy, mathematical modelling, and mathematical analysis of image reconstruction with novel regularization paradigms based on optimal transport. Particular applications include imaging and tracking of macrophages and neutrophils following myocardial ischemia-reperfusion or in arthritis and sepsis with a future potential to translate into clinical algorithms.
