Low SNR and long acquisition times are the primary
hindrance to deployable low-field MRI scanners. .Due to
low Boltzmann polarization, enhancement techniques such
as Dynamic Nuclear Polarization (DNP) and image
acceleration techniques like SENSitivity Encoding
(SENSE) will be vital to obtaining high quality images
in reasonable times. In this study an eight-coil
receive-only array for 6.5 mT was used with a 14 cm
saddle coil and 30 cm NMR Transmit coil to acquire DNP +
SENSE images of a structured phantom. Future work will
improve SENSE reconstruction as well as compare it to
incoherent random undersampling strategies.
