The idea of a very sensitive positron emission tomography (PET) system covering a large
portion of the body of a patient already dates back to the early 1990s. In the period 2000 …

In this review article, we present arguments demonstrating that the advent of high sensitivity
total-body PET systems and the invention of the method of positronium imaging, open …

In vivo assessment of cancer and precise location of altered tissues at initial stages of
molecular disorders are important diagnostic challenges. Positronium is copiously formed in …

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 …

A detection system of the conventional PET tomograph is set-up to record data from
annihilation into two photons with energy of 511 keV, and it gives information on the density …

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 …

Machine learning has found unique applications in nuclear medicine from photon detection
to quantitative image reconstruction. Although there have been impressive strides in …

Recent tests of a single module of the Jagiellonian Positron Emission Tomography system (J-
PET) consisting of 30 cm long plastic scintillator strips have proven its applicability for the …

A novel approach to tomographic data processing has been developed and evaluated using
the Jagiellonian positron emission tomography scanner as an example. We propose a …

Although there have been impressive strides in detector development for time-of-flight
positron emission tomography, most detectors still make use of simple signal processing …
