Organe am Prüfstand

Schematische Darstellung der menschlichen Anatomie mit den Organen, die in Zukunft mit photoakustischer Bildgebung untersucht werden könnten.

Photoakustische Bildgebung zur Bewertung der Qualität von Spenderorganen

In einem von der FFG geförderten, interdisziplinären Forschungsprojekt, in dem Mediziner, Physiker und Techniker aus dem universitären und wirtschaftlichen Umfeld zusammenarbeiten, soll wissenschaftliche Grundlagenforschung in die klinische Routine transportiert werden, um so in Zukunft das Leben vieler Menschen retten zu können.

Robert Nuster und Günther Paltauf vom Fachbereich Experimentalphysik der Karl-Franzens-Universität bringen es auf den Punkt: Ziel dieses Projektes ist die Entwicklung eines photoakustischen bildgebenden Verfahrens zur Erforschung der Mikroperfusion im Schweinemodell und an humanen, nicht transplantablen Organen. Die Abbildung einzelner Blutgefäße, die Charakterisierung der Blutflüsse in peripheren sowie zentralen Regionen, sowie die Messung der Oxygenierung sind einige Daten, die mit der photoakustischen Bildgebung gewonnen werden können. Diese sollen mit gängigen Diagnosemethoden verglichen werden, um eine Korrelation mit molekularbiologischen, immunologischen und histologischen Parametern zu ermöglichen. Durch die somit gewonnene exakte Charakterisierung der Mikroperfusion erwartet man eine bessere Beurteilung der Organqualität. Damit hätte man eine innovative Methode, um Therapieformen zur Verbesserung der Transplantatfunktion zu erproben und würde auf lange Sicht die Anzahl der transplantablen Organe erhöhen.

Kooperationspartner: Transplant Chirurgie der Medizinischen Universität Graz und die Fa. MIDES GmbH

How Fast Is Ultrafast?

In a recent episode of the podcast Bridge the Gap, Tommaso Mazzocchi and Daniel Werner, two graduate physics students, interviewed Peter Puschnig about ultrafast spectroscopy and his current research. The conversation spans fundamental quantum-mechanical concepts and leads up to state-of-the-art methods for observing electronic dynamics in real time. The episode is titled “How fast is ultrafast spectroscopy?” and is aimed at students and anyone interested in modern physics research.

Accelerated communication with the Kanzelhöhe: solar observatory moves closer to the university

From mid-December, the train journey from Graz to Villach will be reduced to just over an hour. This faster railway connection through the Koralm Tunnel will also bring the Kanzelhöhe Observatory for Solar and Environmental Research closer. Although this unique research station at 1500 metres above sea level is located on the Carinthian Gerlitzen, it has been part of the University of Graz for more than 75 years.

Two Awards for an Outstanding Dissertation

Andreas Windischbacher received two prestigious awards for his outstanding doctoral dissertation. On March 17th, 2025, he was presented with the golden ring of honour of the Republic of Austria by our Federal President as part of the Promotio sub auspiciis Praesidentis rei publicae. On the same day, he was also selected for the Josef Krainer Förderungspreis, whose ceremonial presentation, however, took place later on November 12th, 2025.
