The J-PET detector -- a tool for precision studies of ortho-positronium decays
K. Dulski, S. D. Bass, J. Chhokar +41
The J-PET tomograph is constructed from plastic scintillator strips arranged axially in concentric cylindrical layers. It enables investigations of positronium decays by measuremen…
Feasibility study of the positronium imaging with the J-PET tomograph
P. Moskal, D. Kisielewska, C. Curceanu +27
A detection system of the conventional PET tomograph is set-up to record data from e+ e- annihilation into two photons with energy of 511 keV, and it gives information on the densi…
Feasibility study of the time reversal symmetry tests in decays of metastable positronium atoms with the J-PET detector
A. Gajos, C. Curceanu, E. Czerwiński +29
This article reports on the feasibility of testing of the symmetry under reversal in time in a purely leptonic system constituted by positronium atoms using the J-PET detector. The…
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…
Introduction of total variation regularization into filtered backprojection algorithm
L. Raczyński, W. Wiślicki, K. Klimaszewski +30
In this paper we extend the state-of-the-art filtered backprojection (FBP) method with application of the concept of Total Variation regularization. We compare the performance of t…
Three-dimensional image reconstruction in J-PET using Filtered Back Projection method
R. Y. Shopa, K. Klimaszewski, P. Kowalski +30
We present a method and preliminary results of the image reconstruction in the Jagiellonian PET tomograph. Using GATE (Geant4 Application for Tomographic Emission), interactions of…
