This study presents a method for the B1 field flattening and length control of the half-wave dipole antenna for MR imaging with discrete dielectric material coating. To demonstrate this method, we designed a half-wave dipole antenna to operate at 300MHz, including coating the ends of the dipole conductors with a high dielectric material, serving as a way to control the dipole length and electromagnetic field distribution. We also compare the proposed technique with the conventional half-wave dipole antenna and show how the new technique effectively tunes the shorter half-wave dipole antennas at specific frequencies and produces efficient field distributions.

We demonstrate that non-rigid deformations of, e.g., the mouth introduce bias in the vNav-based detection of brain motion, which causes artifacts. We present real-time brain extraction for vNavs and show that these artifacts can be removed by brain-masked registration.
