We propose a design concept for flexible human
head coil arrays, where the array is built into a neoprene EEG cap, and made
of regular-copper flexible wire.
A 32-channel prototype for 13C at 3T
(32.1 MHz) is presented and evaluated, showing SNR performance superior to a 13C-dedicated
volume coil.
Figure 2. Fabricated flexible 32-channel 13C
receive-only array (f = 32.1 MHz), attached to the head phantom used for MR
characterization. The projection of the 7 slices used for the volumetric
characterization is also noted.
Figure 3. SNR maps of the
seven slices covering the whole brain area of the head phantom, and comparison
to the results measured with a reference birdcage coil.
