Abstract This paper examines the dispute between Burge and McDowell over methodology in philosophy of perception. (2005, 2011) has argued that disjunctivism posited by naive perceptual realists is incompatible with results current science, while (2010, 2013) defends his claiming an autonomous field enquiry for epistemology, one does not employ classificatory schemes science. Here it crucial poi...
Background Through-Time Non-Cartesian GRAPPA has been previously demonstrated for real-time 2D cardiac imaging (Seiberlich, et al. Magn Reson Med. 2011 Feb;65(2):492505.). This parallel imaging method works by acquiring several fully-sampled non-Cartesian datasets with a low temporal resolution, and using the coil sensitivity information from these datasets to reconstruct highly undersampled no...
Path generation in Cartesian space is discussed and the idea of using lines and arcs to create general paths is presented. To make smooth paths in Cartesian space zones are introduced and two different ways to interpolate zones are given. An algorithm for transforming a Cartesian path into a cubic spline representation in joint space is presented and also evaluated in an example. An important a...
PURPOSE Evaluate spiral three-dimensional (3D) phase contrast MRI for the assessment of turbulence and velocity in stenotic flow. METHODS A-stack-of-spirals 3D phase contrast MRI sequence was evaluated in vitro against a conventional Cartesian sequence. Measurements were made in a flow phantom with a 75% stenosis. Both spiral and Cartesian imaging were performed using different scan orientati...
