Previous work has demonstrated the advantages of HiSS (complete fat-suppression, improved image …
WebWe explored the minimum spatial resolution requirements for functional magnetic resonance imaging (fMRI) data acquisition when brain mapping is used in neurosurgical planning and navigation. Using a 1.5 Tesla clinical MRI scanner, eight patients with brain … WebThere are two resolution parameters used in MRI for the production of a two dimensional image i.e. basic resolution and phase resolution. Basic resolution. Basic resolution is the number of pixels in the readout direction. Basic resolution also determines the size of the …
Web8. jún 2024 · The 3.0-T DCE MRI whole-brain acquisition protocol described in Bliesener et al was 30-fold undersampled yielding a spatial resolution of 0.9 mm × 1 mm × 2 mm at 5-second temporal resolution. The undersampling occurred in the phase-encoding direction. Web7. nov 2016 · The SFRC characterizes spatial resolution describing the spatial frequency content of an image over a range of frequencies. Verification of the SFRCs was performed on MRI images of Eurospin agarose gel tubes acquired with different resolution settings.
