Quiet
sequences are of particular importance for fetal EPI based imaging,
where the necessary protection of the unborn infant can often
compromise the efficiency and achievable resolution of the EPI
acquisition. This is of particular relevance for connectome type
studies, where long functional and diffusion weighted sequences need
to be acquired in an efficient and safe way.This abstract presents a
quiet SE and GE EPI framework with sinusoidal read-out constant phase
and merged crusher strategy, completely flexible and adaptable to the
scanner impulse response function leading to a decrease of up to
9dB(A).
