Description
The Jagiellonian Positron Emission Tomograph (J-PET) represents the first modular and portable PET scanner capable of multi-photon detection. This multidisciplinary system serves dual purposes in medical imaging and fundamental physics research, including investigations of discrete symmetry violations in positronium decay processes [1,2,3]. Beyond conventional PET imaging capabilities, the J-PET enables positronium lifetime imaging within the human body [4,5,6]. The recent achievement of capturing the first in-vivo positronium image in human brain tissue using J-PET technology [6] demonstrates the promising future of this novel diagnostic approach. The most suitable radiopharmaceutical for this type of imaging would be one with the 44Sc radioisotope [7], and work is currently underway on the preparation of a Scandium generator [8] and the development of this tracer.
My presentation will cover research conducted with the J-PET facility spanning both fundamental physics studies and medical imaging applications.
