متن کاملHuman Brain Imaging at 9.4 Tesla Using a Combination of Traveling Wave Excitation with a 15-channel Receive-only Array
Introduction The combination of a circularly polarized (CP) volume coil for spin excitation with a multi-channel receive-only array is a successful setup for routine human brain imaging at 7 Tesla. For reception, the use of multiple surface coils is important for a high SNR and for the utilization of parallel imaging techniques. For transmission, the main strength of the CP coil is the reasonab...
متن کاملThree Dimensional Spectroscopic Imaging in the Prostate with a Surface Combined Endorectal Coil at 7 Tesla
INTRODUCTION: The benefits of performing prostate spectroscopy at 7T include increased spectral and spatial resolution. The potential exists to be able to better quantify individual metabolites, localize smaller volumes of disease and better monitor disease progression or treatment response. However, spectroscopy in the body at 7T faces many challenges including the well described destructive i...
متن کاملA 16-Channel Receive, Forced Current Excitation Dual-Transmit Coil for Breast Imaging at 7T
PURPOSE To enable high spatial and temporal breast imaging resolution via combined use of high field MRI, array coils, and forced current excitation (FCE) multi channel transmit. MATERIALS AND METHODS A unilateral 16-channel receive array insert was designed for use in a transmit volume coil optimized for quadrature operation with dual-transmit RF shimming at 7 T.

متن کاملDesign and comparison of two eight-channel transmit/receive radiofrequency arrays for in vivo rodent imaging on a 7 T human whole-body MRI system.
PURPOSE Magnetic resonance imaging (MRI) of rodents can be expected to be a growing application, particularly when translatory imaging research "from mouse to man" is envisioned. 7 T high-field human whole-body MR systems provide a powerful platform for high-resolution small animal imaging. For achieving adequate spatial resolution, dedicated radiofrequency coils have to be designed to provide ...
