A Monte Carlo positronium decay source model with multiple annihilation channels in GATE
Wojciech Krzemien, Mateusz Bala, Kamil Dulski +7
Positronium-based imaging requires realistic modelling of positronium (Ps) decay in matter. We introduce a modular Ps decay model implemented in GATE 9.4 and GATE 10, enabling the…
Development of the normalization method for the first large field-of-view plastic-based PET Modular scanner
A. Coussat, W. Krzemien, J. Baran +4
In positron emission tomography acquisition (PET), sensitivity along a line of response can vary due to crystal geometrical arrangements in the scanner and/or detector inefficienci…
Investigation of Novel Preclinical Total Body PET Designed With J-PET Technology:A Simulation Study
M. Dadgar, S. Parzych, F. Tayefi Ardebili +29
The growing interest in human-grade total body positron emission tomography (PET) systems has also application in small animal research. Due to the existing limitations in human-ba…
Optimisation of the event-based TOF filtered back-projection for online imaging in total-body J-PET
R. Y. Shopa, K. Klimaszewski, P. Kopka +24
We perform a parametric study of the newly developed time-of-flight (TOF) image reconstruction algorithm, proposed for the real-time imaging in total-body Jagiellonian PET (J-PET)…
Towards 2+1 photon tomography: Energy-based selection of two 511 keV photons and a prompt photon with the J-PET scanner
R. Masełek, W. Krzemien, K. Klimaszewski +31
The possibility to separate signals caused by 511 keV photons created in annihilation of electron-positron pairs and the so-called prompt photons from nuclei de- excitation is inve…
Human Tissues Investigation Using PALS Technique
B. Jasińska, B. Zgardzińska, G. Chołubek +34
Samples of uterine leiomyomatis and normal tissues taken from patients after surgery were investigated using the Positron Annihilation Lifetime Spectroscopy (PALS). Significant dif…
