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…
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…
A Conjugate Bayesian Framework for Fast 3D Positronium Lifetime Estimation with a Partial System Matrix
Berkin Uluutku, Giulianno Gasparato, Manish Das +7
Background: Positronium lifetime imaging extends conventional positron emission tomography by using the time interval between positron emission and annihilation as an additional co…
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…
First ex-vivo positronium imaging of tissues with modular J-PET scanner using Sc radionuclide
Karol Kubat, Manish Das, Sushil Sharma +41
This study presents the first ex-vivo positronium imaging of human tissues using the modular J-PET scanner with the Sc radionuclide. The Sc isotope was produced via t…
