A multi-echo pseudo-golden
angle stack of stars sequence is investigated for use in MR thermometry. High
spatial and temporal resolution is achieved through k-space filtering. PRF
temperature, T2*, ρ (signal magnituade at TE = 0), respiration correction and fat/water separation are
simultaneously measured. Use of a pseudo-golden angle increment allows for the
removal of phase (and therefore PRF temperature) artifacts due to changing
k-space sampling between reconstructed time points. k-Space sampling based phase
reference greatly improves temperature standard deviation. FUS heating
experiments are performed while simulating respiration artifacts.
