Abstract: A system and method for adaptive averaging of velocity spectra using variable density trajectories, comprising: acquiring at least one series of velocity spectra using interleaved variable density trajectories and sampling low kv data more often or more densely than high kv data, the series of velocity spectra further comprising at least one spectrum; identifying a series of velocity spectra that comprises at least one velocity spectrum as a template, aligning at least one of the acquired series of velocity spectra with the template using low kv data; and averaging the aligned spectra, the averaging further comprising averaging the low kv data of the aligned spectra, and combining the averaged low kv data with the high kv data of the aligned spectra, wherein the combination produces enhanced spectra.
