Magnetic resonance cholangiopancreatography (MRCP) uses magnetic resonance (MR) pulse sequences in which static fluid appears bright against a low signal or dark background. When these MR images are subjected to postprocessing techniques, they produce images that resemble the pancreatograms obtained using endoscopic retrograde cholangiopancreatography(More)
MAXIMA is a balloon-borne platform for measuring the anisotropy of the Cosmic Microwave Background (CMB). It has measured the CMB power spectrum with a ten-arcminute FWHM beam, corresponding to a detection of the power spectrum out to spherical harmonic multipole l ∼ 1000. The spectrum is consistent with a flat Universe with a nearly scale-invariant initial(More)
Measurement of the arterial input function (AIF) is essential to deriving quantitative estimates of regional myocardial blood flow using kinetic models. Accurate measurements have been possible with a wide range of radiotracers in both research and clinical PET/CT imaging. However, accurate measurements of the AIF with dynamic SPECT or SPECT/CT have posed(More)
Computer simulations, a phantom study and a human study were performed to determine whether a slowly rotating single-photon computed emission tomography (SPECT) system could provide accurate arterial input functions for quantification of myocardial perfusion imaging using kinetic models. The errors induced by data inconsistency associated with imaging with(More)
Our collaboration has designed, installed, and operated a compact antineutrino detector at a nuclear power station, for the purpose of monitoring the power and plutonium content of the reactor core. This paper focuses on the basic properties and performance of the detector. We describe the site, the reactor source, and the detector, and provide data that(More)
