SERIAL excitation produces uniform image intensity at low power at ultra high field but has not been applied to humans. FLASH sequences modified for sequential single coil excitation while retaining full array receive mode were combined with generalized total variation regularized SENSE reconstruction and 4- and 8- arrayed coils. Images with acceptable uniformity, contrast and resolution over the in vivo human brain are demonstrated at 9.4T using low power.
