Effect of subject‐specific head morphometry on specific absorption rate estimates in parallel‐transmit MRI at 7 T

Purpose To assess the accuracy of morphing an established reference electromagnetic head model to a subject‐specific morphometry for the estimation of specific absorption rate (SAR) in 7T parallel‐transmit (pTx) MRI. Methods Synthetic T1‐weighted MR images were created from three high‐resolution ope...
