Computed tomography (CT) is responsible for much of the radiation exposure to the population for medical purposes. The technique requires high doses that vary widely from center to center, and for different scanners and radiologists as well. In order to monitor doses to patients, the American Association of Physicists in Medicine has developed the(More)
PURPOSE To propose a magnetic resonance imaging (MRI) quality assurance procedure that can be used for multicenter comparison of different MR scanners for quantitative diffusion-weighted imaging (DWI). MATERIALS AND METHODS Twenty-six centers (35 MR scanners with field strengths: 1T, 1.5T, and 3T) were enrolled in the study. Two different DWI acquisition(More)
Radar data collected at an experimental facility arranged on purpose suggest that the footprint of atmospheric turbulence might be encoded in the radar signal statistics. Radar data probability distributions are calculated and nicely fitted by a one-parameter family of generalized Gumbel (GG) distributions, Ga. A relation between the wind strength and the(More)
