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…
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…
J-PET: a new technology for the whole-body PET imaging
S. Niedźwiecki, P. Białas, C. Curceanu +30
The Jagiellonian Positron Emission Tomograph (J-PET) is the first PET built from plastic scintillators. J-PET prototype consists of 192 detection modules arranged axially in three…
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…
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…
Time calibration of the J-PET detector
M. Skurzok, M. Silarski, D. Alfs +32
The Jagiellonian Positron Emission Tomograph (J-PET) project carried out in the Institute of Physics of the Jagiellonian University is focused on construction and tests of the firs…
