Parallel imaging in the Johnson noise dominated regime is a new regime; optimal parameters are not available in the literature. In this study, an eight-coil receive only array for 6.5 mT was constructed and SENSE was used to accelerate images. An 8 channel receive only array was constructed from 8 cm, 30 turn, 24 gage wire inductive coils. The correlation coefficient matrix was almost the identity matrix. SENSE with a reduction factor of 2 was simulated and then acquired and images were successfully reconstructed. Future work will attempt higher reduction factors and combine SENSE with random undersampling.
