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…
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…
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…
Studies of CPT symmetry in positronium decays with 192 plastic strip J-PET detector
N. Chug, S. D. Bass, E. Y. Beyene +40
A direct test of the CPT symmetry is performed for the electromagnetic decays of ortho-positronium using the J-PET tomograph. We present the precise measurement of the CPT-sensitiv…
