Offer Description

The research group of Prof. Ewa Stępień invites applications for a postdoctoral position in the OPUS project entitled "High-throughput PET imaging by decoding multi-photon signals on long axial field-of-view PET using physics-guided artificial intelligence"

This Polish-Swiss collaborative project aims to achieve a breakthrough in positronium lifetime imaging using a clinical PET scanner combined with artificial intelligence. While conventional PET measures only radiotracer concentration, recording multi-photon annihilation reveals critical details about the tissue microenvironment. A major challenge- complex image reconstruction and low triple-coincidence statistics- will be addressed by developing physics-informed deep learning models. Focused on prostate cancer imaging, the research integrates Monte-Carlo simulations, phantom measurements, and histopathology across cell cultures, animal models, and clinical patients. The expected results include the first-ever clinical positronium imaging of prostate cancer, novel acquisition protocols, and deep insights into the underlying pathophysiology. Ultimately, this methodology will enhance PET diagnostic accuracy and throughput while reducing patient radiation exposure and operational costs.
