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.
