Keywords: RF Arrays & Systems, System Imperfections: Measurement & CorrectionFrequency translation has been demonstrated to enable X-nuclear array coils on systems with only narrow-band 1H receivers. Mixing on receive only is preferred given the SAR monitoring on the transmit side, but requires additional phase correction to perform signal averaging. A post-processing phase correction method has been previously introduced by our group using the signals coupled from the local oscillators (LO) on the host system and translator. To avoid any post-processing and improve scanner throughput, we implement this correction method with hardware to detect and compensate the phase shift during the scan, which allows the signal averaging on the scanner.
