A low-field imager offers a potentially transportable and rapidly deployable human imaging system without many of the system requirements of typical scanners. The aim of this study was to construct an 8-channel receive-only helmet array for imaging the human brain. The helmet was 3D printed. Coils consisted of 4x12 cm and 4x14 cm loops, each with 30 turns of 24 AWG copper wire. Geometric decoupling between nearest neighbors was at least -30 db while next nearest neighbors was -6 dB. Future work will compare parallel imaging to incoherent random undersampling and SENSE.
