Searches for discrete symmetries violation in ortho-positronium decay using the J-PET detector
D. Kamińska, T. Bednarski, P. Białas +24
In this paper we present prospects for using the J-PET detector to search for discrete symmetries violations in a purely leptonic system of the positronium atom. We discuss tests o…
Studies of unicellular micro-organisms Saccharomyces cerevisiae by means of Positron Annihilation Lifetime Spectroscopy
E. Kubicz, B. Jasińska, B. Zgardzińska +26
Results of Positron Annihilation Lifetime Spectroscopy (PALS) and microscopic studies on simple microorganisms: brewing yeasts are presented. Lifetime of ortho - positronium (o-Ps)…
Reconstruction of hit-time and hit-position of annihilation quanta in the J-PET detector using the Mahalanobis distance
N. G. Sharma, M. Silarski, T. Bednarski +24
The J-PET detector being developed at Jagiellonian University, is a Positron Emission Tomograph composed of the long strips of polymer scintillators. At the same time it is a detec…
PALS investigations of free volumes thermal expansion of J-PET plastic scintillator synthesized in polystyrene matrix
A. Wieczorek, B. Zgardzińska, B. Jasińska +25
The polystyrene dopped with 2,5-diphenyloxazole as a primary fluor and 2-(4-styrylphenyl)benzoxazole as a wavelength shifter, prepared as a plastic scintillator was investigated us…
Processing optimization with parallel computing for the J-PET tomography scanner
W. Krzemień, M. Bała, T. Bednarski +27
The Jagiellonian-PET (J-PET) collaboration is developing a prototype TOF-PET detector based on long polymer scintillators. This novel approach exploits the excellent time propertie…
Application of the Compress Sensing Theory for Improvement of the TOF Resolution in a Novel J-PET Instrument
L. Raczynski, P. Moskal, P. Kowalski +24
Nowadays, in Positron Emission Tomography (PET) systems, a Time of Flight information is used to improve the image reconstruction process. In Time of Flight PET (TOF-PET), fast det…
