Download or read book Quantitative MR Imaging of the Electric Properties and Local SAR Based on Improved RF Transmit Field Mapping written by Tobias Voigt and published by KIT Scientific Publishing. This book was released on 2014-08-18 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents three new quantitative methods for magnetic resonance imaging. A method for simultaneous mapping of B1 and T1 (MTM) is developed and validated. Electric Properties Tomography (EPT), a method for quantitative imaging of dielectric properties of tissue, is presented. Based on EPT, separate (phase-based) conductivity and (amplitude-based) permittivity measurements are introduced. Finally, a B1-based method for patient-specific local SAR measurements is presented.
