SAR Reduction in 7T C-Spine Imaging Using a “Dark Modes” Transmit Array Strategy
PURPOSE: Local specific absorption rate (SAR) limits many applications of parallel transmit (pTx) in ultra high-field imaging. In this Note, we introduce the use of an array element, which is intentionally inefficient at generating spin excitation (a “dark mode”) to attempt a partial cancellation of...
