a, Photographs of the 72-channel in vivo receive array (top), birdcage transmit coil (middle) and integrated coil assembly (bottom). Field probes (16-channel 19F) are accurately positioned throughout the receive array to capture higher-order field terms. b, Photographs of the 64-channel ex vivo whole-brain coil (top and middle) and integrated coil assembly with ventilation tubes for temperature control (bottom). c, SNR maps of the 72-channel (72ch) in vivo coil compared to a 32-channel (32ch) standard coil. d, SNR maps of the 64-channel (64ch) ex vivo coil compared to the 72-channel in vivo coil. e, Image-encoding capability for accelerated imaging represented as noise amplification in g-factor maps (1/g) of the 72-channel in vivo coil compared to a 32-channel standard coil at different levels of acceleration R. f, g-factor maps of the 64-channel ex vivo coil compared to the 72-channel in vivo coil.
