An efficient method to generate 3-dimensional maps of
tissue electrical properties (TEP's) is demonstrated. It
relies on two fundamental tenets: a recent reformulation
of the Helmholtz equations (requiring only the complex
value of the transceive field for TEP computation), and
ZTE imaging (providing a legitimate estimate of the
complex transceive field in a SNR efficient manner).
Phantom and in vivo results obtained from the brain of a
normal volunteer are presented.
