Tissue electrical properties (TEP) can be calculated
from RF-induced complex image intensity variation in
standard MR images. Whereas conventional B1 map-based
TEP mapping relies on a transmit/receive birdcage coil,
the image-based method allows use of multichannel
receiver arrays for higher SNR. Here we demonstrate the
principle of image-based TEP mapping with a
multi-channel receiver array with optimized phase
weighting.
