MR Systems Engineering: RF Interactions

IMPORTANT PREAMBLE • RF Interactions impacts the vast majority of components involved in RF Transmit and RF Receive chains in an MR system. • This lecture, however, will deliberately focus on RF Interactions occurring at the level of a sample imaged with Receive and/or Transmit RF Coil Arrays consisting of multiple Receive and/or Transmit RF Coil Elements driven by individual RF Channels. • This lecture will mostly concern Human MR Imaging in Humans where RF wavelength can approach the size of, or be smaller than, the dimensions of the imaged sample. • Most sections of this lecture will be supported by experimental results and simulations run in MatlabTM to illustrate different levels of RF Interaction concepts • A complete bibliography would include hundreds of publication. Thus, a shorter list of papers will be found at the end of the present Syllabus, including numerous seminal paprts; additional updated references will be given at the end of the lecture.
