Controlling induced currents in guidewires using parallel transmit
Introduction: Conductive structures, such as guidewires and implanted device leads, present a safety hazard in MRI. The coupling between these structures and the RF transmit field can result in currents being induced, which can lead to dangerous heating [1, 2]. In previous work [3], it was shown that the magnitude and phase of current induced in a wire depends on the position of the RF coil wit...
متن کاملCorrection of B0 induced slice profile distortion using parallel transmit
Introduction: With the advent of parallel transmit (PTx), there has been much interest in creating complex spatially localised excitations. The algorithms which calculate the requisite pulses [1,2] require an estimate of the B1 field produced by each coil, and also a map of the B0 (off resonance) field, since this distorts the excited magnetisation profiles. In fact spatially localized excitati...
متن کاملA Parallel Transmit Volume Coil With Independent Control of Currents on the Array Elements
K. N. Kurpad, E. B. Boskamp, S. M. Wright Electrical Engineering, Texas A&M University, College Station, Texas, United States, Applied Science Laboratory, GE Healthcare, Waukesha, Wisconsin, United States Introduction The dielectric property of tissues shortens the wavelength of the RF magnetic field in the body. It tends to produce significant inhomogeneity in B1 distribution at high frequency...
متن کاملSparse Parallel Transmit Pulse Design Using Orthogonal Matching Pursuit Method
Introduction Parallel RF transmit (Tx) offers additional degrees of freedom (redundancy) in excitation pulse design [1,2]. One application of this redundancy is accelerating multidimensional selective excitation by under-sampling the excitation k space. Unlike the spatial encoding task in imaging, where the underlying image is unknown, in the case of excitation pulse design the target excitatio...
متن کاملControlling currents through molecular wires
We investigate the possibility of controlling by means of external laser fields both the current through molecular wires and the corresponding noise properties. It is found that an appropriate off-resonant driving field reduces the coherent transport across the molecule resulting in a strong current suppression. The relative level of transport noise, characterized by a Fano factor, exhibits cha...
