SAR reduction in 7T C-spine imaging using a “dark modes” transmit array strategy

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...
