Proton (1H)‐MRSI via spatial‐spectral encoding poses high demands on gradient hardware at ultra‐high fields and high‐resolutions. Rosette trajectories help alleviate these problems, but at reduced SNR‐efficiency because of their k‐space densities not matching any desired k‐space filter. We propose modified rosette trajectories, which more closely match a Hamming filter, and thereby improve SNR performance while still staying within gradient hardware limitations and without prolonging scan time.
