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…
Commissioning of the J-PET detector for studies of decays of positronium atoms
E. Czerwiński, K. Dulski, P. Białas +29
The Jagiellonian Positron Emission Tomograph (J-PET) is a detector for medical imaging of the whole human body as well as for physics studies involving detection of electron-positr…
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…
Multichannel FPGA based MVT system for high precision time (20~ps~RMS) and charge measurement
M. Pałka, P. Strzempek, G. Korcyl +29
In this article it is presented an FPGA based ulti-oltage hreshold (MVT) system which allows of sampling fast signals ( ns rising and falling edge) in both voltage an…
