QUASAR™ MRID3D is a new, patent pending, cost-effective QA system for quantifying geometric distortion in 3D MR images. Analysis is performed on images for diagnostic and guidance applications. Unlike other distortion analysis products, which only sample a few imaging planes, QUASAR™ MRID3D analyzes the entire 3D field of view in a single acquisition. A publication in Medical Physics is available online: http://dx.doi.org/10.1118/1.4898582. The results have been verified by comparison to a custom high density 3D grid phantom. Novel method based on 3D harmonic analysis of distortion •...
