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