BACKGROUND AND PURPOSE:
The adoption of routine clinical 7T MRI has been constrained by several challenges, with heterogeneity of the transmit field (B1+) being among the most notable. Dynamic parallel transmission (pTx) presents a promising strategy to enhance B1+ transmit homogeneity; however, associated technical challenges have limited its routine use. We assess performance of a prototype dynamic pTx implementation for the 3D sampling perfection with application-optimized contrasts by using …
