Abstract Purpose To investigate inter-subject variability of B1+, SAR and temperature rise in a database of human models using a local transmit array for 7 T cardiac imaging. Methods Dixon images were acquired of 14 subjects and segmented in dielectric models with an eight-channel local transmit array positioned around the torso for cardiac imaging. EM simulations were done to calculate SAR distributions.

1 INTRODUCTION Imaging of the breast at 7 T is of interest due to the increased spectral and spatial resolution, enabling characterization of breast cancer and monitoring of treatment. However, breast imaging at 7 T is challenging mainly due to severe non‐uniformities in RF transmit (B1+) fields1-3 and limited penetration depth.
