Sensitivity profile of the RF coils measured using a bottle container of corn oil (1.1% natural abundance of ¹³C) and a ball phantom of ¹³C‐labeled 1‐M HCO₃ ⁻. (A) ¹H MRI showing the positioning of the phantoms relative to the transmit clamshell and 8‐channel receive paddle‐shaped phased‐array ¹³C RF coils. (B) Coil‐wise reconstructed total ¹³C maps acquired using a free‐induction decay chemical shift imaging sequence with a nonselective 90‐degree angle RF pulse. (C) Spatially averaged coil‐wise magnitude spectra. Abbreviations: ch, channel; RX, receive; TX, transmit.
