Comparative studies of plastic scintillator strips with high technical attenuation length for the total-body J-PET scanner
L. Kaplon, J. Baran, N. Chug +31
Plastic scintillator strips are considered as one of the promising solutions for the cost-effective construction of total-body positron emission tomography, (PET) system. The purpo…
Comparative studies of the sensitivities of sparse and full geometries of Total-Body PET scanners built from crystals and plastic scintillators
Meysam Dadgar, Szymon Parzych, Jakub Baran +28
Background: Total-Body imaging offers high sensitivity, single-bed position, and low dose, but high construction costs limit worldwide utilization. This study compares existing and…
TOF MLEM Adaptation for the Total-Body J-PET with a Realistic Analytical System Response Matrix
R. Y. Shopa, J. Baran, K. Klimaszewski +32
We report a study of the original image reconstruction algorithm based on the time-of-flight maximum likelihood expectation maximisation (TOF MLEM), developed for the total-body (T…
Simulating NEMA characteristics of the modular total-body J-PET scanner -- an economic total-body PET from plastic scintillators
Paweł Moskal, Paweł Kowalski, Roman Shopa +26
The purpose of the presented research is estimation of the performance characteristics of the economic Total-Body Jagiellonian-PET system (TB-J-PET) constructed from plastic scinti…
Hit-time and hit-position reconstruction in strips of plastic scintillators using multi-threshold readouts
N. G. Sharma, M. Silarski, J. Chhokar +32
In this article, a new method for the reconstruction of hit-position and hit-time of photons in long scintillator detectors is investigated. This research is motivated by the recen…
Development of J-PEM for breast cancer detection and diagnosis using positronium imaging
Shivani, Elżbieta Luczyńska, Sylwia Heinze +1
The purpose of the presented investigations is to design, construct and establish the characteristic performance of the Jagiellonian Positron Emission Mammography(J-PEM), being des…
Estimating relationship between the Time Over Threshold and energy loss by photons in plastic scintillators used in the J-PET scanner
S. Sharma, J. Chhokar, C. Curceanu +36
Time-Over-Threshold (TOT) technique is being used widely due to its implications in developing the multi channel readouts mainly when fast signal processing is required. Using TOT…
Performance assessment of the 2 positronium imaging with the total-body PET scanners
P. Moskal, D. Kisielewska, Z. Bura +39
In living organisms the positron-electron annihilation (occurring during the PET imaging) proceeds in about 30% via creation of a metastable ortho-positronium atom. In the tissue,…
Estimating the NEMA characteristics of the J-PET tomograph using the GATE package
Paweł Kowalski, Wojciech Wiślicki, Roman Shopa +30
The novel whole-body PET system based on plastic scintillators is developed by the {J-PET} Collaboration. It consists of plastic scintillator strips arranged axially in the form of…
Analysis procedure of the positronium lifetime spectra for the J-PET detector
K. Dulski, B. Zgardzinska, P. Bialas +30
Positron Annihilation Lifetime Spectroscopy (PALS) has shown to be a powerful tool to study the nanostructures of porous materials. Positron Emissions Tomography (PET) are devices…
