Experimental determination of the Dalitz plot for positronium decay using the J-PET detection system

M. Skurzok, Steven D. Bass, Kamila Kasperska, Ermias Beyene et autres

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 uncertainty in angular representation over almost the entire available phase space, were performed using the Jagiellonian Positron …

Feasibility simulation study of positronium lifetime imaging with the Biograph Vision Quadra and J-PET tomographs

S. Parzych, Szymon Niedźwiecki, E. Beyene, N. Chug et autres

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 sensitivity Positron Emission Tomography (PET) systems are needed for PLI since it requires simultaneous registration of annihilation photons and …

First-in-human quantum entanglement imaging

P Moskal, Deepak Kumar, Sharma, S, K, Ermias Y. Beyene et autres

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 degree of quantum entanglement of photons originating from positron-electron annihilation within a human subject. This …

First positronium lifetime imaging using 52Mn and 55Co with a plastic-scintillator-based PET scanner

Manish Das, Sushil Sharma, E. Beyene, Aleksander Bilewicz et autres

This study demonstrates the applicability of [Formula: see text]Mn and [Formula: see text]Co radionuclides for positronium imaging. Positronium Lifetime Imaging (PLI) extends positron emission tomography by using the lifetime of positronium atoms as a probe of tissue molecular architecture. However, its practical …

Monte Carlo-based scatter correction for the plastic-based modular PET scanner J-PET

Reimund Bayerlein, Manish Das, Sushil Sharma, Ramsey Derek Badawi et autres

Abstract Objective. This work presents and evaluates a Monte Carlo (MC) -based scatter correction (SC) method developed for the Jagiellonian positron emission tomography (J-PET) scanner, a modular PET system based on plastic scintillators. Approach. The algorithm employs SimSET-based simulations integrated into a …

First ex-vivo positronium imaging of tissues with modular J-PET scanner using $^{44}$Sc radionuclide

Karol Kubat, Manish Das, Sushil Sharma, E. Beyene et autres

This study presents the first ex-vivo positronium imaging of human tissues using the modular J-PET scanner with the $^{44}$Sc radionuclide. The $^{44}$Sc isotope was produced via the $^{44}$Ca(p, n)$^{44}$Sc nuclear reaction and used to perform positronium imaging of phantom composed of human …
