Noel C. Codella¹, Pascal Spincemaille², Martin Prince², Yi Wang²

This work proposes a rapid self-calibrating radial GRAPPA method that eliminates the need to change domains, calculate sensitivity maps, generate synthetic calibration data, or perform extra gridding operations before the derivation of the GRAPPA kernels.
