Discrete symmetries tested at 10 precision using linear polarization of photons from positronium annihilations
PaweÅ Moskal, Eryk CzerwiÅski, Juhi Raj +38
Discrete symmetries play an important role in particle physics with violation of CP connected to the matter-antimatter imbalance in the Universe. We report the most precise test of…
Realistic Total-Body J-PET Geometry Optimization -- Monte Carlo Study
Jakub Baran, Wojciech Krzemien, Lech RaczyÅski +31
Total-Body PET is one of the most promising medical diagnostics modalities. The high sensitivity provided by Total-Body technology can be advantageous for novel tomography methods…
Feasibility of the J-PET to monitor range of therapeutic proton beams
Jakub Baran, Damian Borys, Karol BrzeziÅski +40
Objective: The aim of this work is to investigate the feasibility of the Jagiellonian Positron Emission Tomography (J-PET) scanner for intra-treatment proton beam range monitoring.…
First-in-human quantum entanglement imaging
Pawel Moskal, Deepak Kumar, Sushil Sharma +37
Annihilation photons are quantum-entangled in polarization, a phenomenon that has not been exploited in medical diagnostics so far. We present the first in vivo imaging of the degr…
First Positronium Lifetime Imaging using Mn and Co with a plastic-based PET scanner
Manish Das, Sushil Sharma, Ermias Yitayew Beyene +45
Positronium Lifetime Imaging (PLI) extends positron emission tomography by using the lifetime of positronium atoms as a probe of tissue molecular architecture. In this work, we rep…
Testing CPT symmetry in ortho-positronium decays with positronium annihilation tomography
PaweÅ Moskal, Aleksander Gajos, Muhsin Mohammed +35
Charged lepton system symmetry under combined charge, parity, and time-reversal transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic limits, discr…
First positronium imaging using Sc with the J-PET scanner: a case study on the NEMA-Image Quality phantom

Positronium Lifetime Imaging (PLI), an emerging extension of conventional positron emission tomography (PET) imaging, offers a novel window for probing the submolecular properties…
Feasibility study of the positronium lifetime imaging with the Biograph Vision Quadra and J-PET tomographs
Szymon Parzych, Szymon Niedźwiecki, Ermias Yitayew Beyene +39
Background: After its first ex-vivo and in-vivo demonstration, Positronium Lifetime Imaging (PLI) has received considerable interest as a potential new diagnostic biomarker. High s…
Modular J-PET with Improved o-Ps Detection Efficiency for CPT Tests
Neha Chug, Aleksander Gajos
J-PET is a photon detector built of plastic scintillators, which already has been commissioned for CPT studies in the decays of positronium. In the first experiment, J-PET has achi…
Experimental determination of the Dalitz plot for positronium decay using the J-PET detection system
Magdalena Skurzok, Steven D. Bass, Kamila Kasperska +37
We present the first measurements of the Dalitz plot for ortho-positronium annihilation to three photons. Our measurements, accurate to about 3% statistical and 2-3% systematic unc…
