Synopsis

23Na and 31P spectroscopy are powerful tools in assessing muscles in Duchenne Muscular Dystrophy studies. Frequency translation has been previously introduced as a means to facilitate multichannel studies on systems equipped with only 1H receiver arrays. Many approaches to frequency translation require mixing on both transmit and receive, which bypasses the need for phase correction. Presented here is an approach to receive-only translation of acquired data to the 1H frequency, that allows for post-processing phase correction using signals coupled from the host system’s and translator’s local oscillators.
