A densely packed 32-channel motor cortex array coil was designed, constructed and compared to a 32-channel whole-head coil at 7T. The developed design allows coil adaptability to a wide range of head sizes, thereby minimizing the distance of the brain to the individual small loop elements. Using the high SNR and parallelism afforded by this array, a substantial gain in sensitivity and performance for imaging the human motor cortex was achieved, enabling 0.15x0.15x0.65 mm³ resolution SWI scans.
