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 …

Exploring nucleon-induced reactions on Selenium-80 using COMPLET code

Teshale Ayalew Mekuriaw, Yihunie Hibstie Asres, Senamaw Mequanent Zegeye, E. Beyene

The variation of nuclear reaction cross-sections with the variation in projectile energies is called excitation functions has been a subject of great interest since last few decades. They beautifully display the pre-equilibrium as well as equilibrium emission of particles. Nucleon-induced reactions on …

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 …
