COVID-19 clinical presentation and prognosis are highly variable, ranging from
asymptomatic and paucisymptomatic cases to acute respiratory distress syndrome and multi-organ …

We recently demonstrated in a clinical trial the ability of a new protocol, IQ SPECT, to
acquire myocardial perfusion imaging (MPI) studies in a quarter of the time (12 s/view) of the …

Background We have recently validated a quarter-time protocol in Myocardial Perfusion
Imaging named IQ-SPECT, whose basic principle is to implement a multifocal collimator; …

Aims and background The purpose of this study was to investigate the palliative effectiveness
of an interstitial fractionated high-dose-rate (HDR) brachytherapy regimen in patients with …

MATERIALS AND METHODS Twenty-six patients with ATN were studied. Seventeen had
elevated concentrations of free thyroxine (FT4) or free triiodothyronine (FT3) in serum (toxic …

This paper introduces a new control technique for power factor correction in ac-dc converters.
It combines the advantages of conventional hysteresis control strategy and the prominent …

This paper proposes a single-phase boost-type three-level rectifier employing a passive
nondissipative snubber. The converter is supposed to present high input power factor, low …

Background We developed a software for evaluating several TG-142 parameters from EPID
images, based on the free python package Pylinac (github. com/jrkerns/pylinac). The …

In this work the egsnrc Monte Carlo code was used to calculate the parameters of the aapm
tg60 report formalism for the dosimetry of a beta source used in intravascular brachytherapy. …

Background. We have recently validated a quarter-time protocol in Myocardial Perfusion
Imaging named IQ-SPECT, whose basic principle is to implement a multifocal collimator; …
