Issues with radiofrequency heating in MRI
To the Editor: In recent years, the use of magnetic resonance imaging (MRI) has been increasing in patients with implanted devices, such as cardiac pacemakers and neurostimulators, which used to preclude the use of MRI owing to patient safety and device malfunction concerns.(1-6) In the past few years, however, more of these implant devices have become MR-compatible and can function properly du...
متن کاملParallel Transmit Technology for High Field MRI
The success of parallel reconstruction methods and their impact on image encoding has sparked a great deal of interest in using the spatial distribution of transmit coils in an analogous fashion. Namely, by breaking down the transmit field into multiple regions each controlled by a separate transmit channel, spatial degrees of freedom are created that allow the spatial information in the array ...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Slot-line antenna array for high field parallel transmit MRI
Objective Parallel transmission is receiving more and more attention in MRI, and multi-element transmit MRI systems become commercially available. A number of different Tx/Rx antenna types have been presented for usage in parallel transmit configurations: degenerate birdcage coils, decoupled TEM or stripline coils [1,2,3]. All of these ‘traditional’ coil-types have their pro’s and con’s. We pro...
