TY - GEN AU - Voigt,Tobias TI - Quantitative MR Imaging of the Electric Properties and Local SAR based on Improved RF Transmit Field Mapping SN - KSP/1000020953 PY - 2011/// PB - KIT Scientific Publishing KW - Magnetic Resonance Imaging KW - permittivity imaging KW - conductivity imaging KW - local specific absorption rate imaging N1 - Open Access N2 - 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 UR - https://www.ksp.kit.edu/9783866445987 UR - https://directory.doabooks.org/handle/20.500.12854/57440 ER -
