A dense, form-optimized 32-channel visual cortex array
coil was constructed and compared to a commercial
32-channel brain coil at 3T. The array coil provides
substantial gain in cortical SNR in accelerated imaging
acquisitions. The coil allows for sub-millimeter
functional imaging using a conventional sequence, and
the resulting images empowered high-resolution mapping
and measurement of visually-driven activity with minimal
pre-processing.
