background: aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (vmat/rapidarc) using 2d planar dosimetry, dynalog files and compass 3d dosimetry system. materials and methods: pre-treatment quality assurance of 10 gated vmat plans was verified using 2d array and compass 3d dosimetry system. advantage of compass over 2d planar is that it provides the clin...

We propose a time-gated-single-pixel-camera as promising sensor for image-free object detection automotive application in adverse weather conditions. By combining the well-known principles of time-gating and single-pixel with neural networks, we aim to ultimately detect objects within scene rapidly robustly low-cost sensor. Here, evaluate possible data reduction such system can provide compared...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

OBJECTIVES We assessed the ability of anti-cyclic citrullinated peptide (CCP) tests to diagnose rheumatoid arthritis (RA), comparing the effect of manufacturer assay type, study design (single- and two-gated) and duration of disease (early vs. established). METHODS We searched seven databases for relevant diagnostic studies containing data on CCP tests in known or suspected RA patients. We us...

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...
