An integrated transmit coil and four-element receive array has been simulated, constructed, characterized and tested on a low field MRI system operating at 2.15 MHz. Using a combination of loops and butterfly coils neighbouring inter-element coupling is below -18 dB, with directly opposite coils ~-9 dB, and <-17 dB coupling for all receive coils to the transmit coil. Images of a phantom have been acquired with a simple sum-of-squares reconstruction.
