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

Abstract:

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 open-source electromagnetic head voxel models. The accuracy of morphing a “reference” (multimodal image-based detailed an...
