Recently, a developed approach to faster imaging has
been spatial encoding with nonlinear magnetic fields,
such as, PatLoc, O-Space, Null Space, 4D-RIO, etc. But,
these efforts have focused on gradient echo imaging.
Otherwise, Turbo Spin Echo (TSE) sequences provide much
faster scan time than standard spin echo sequences. In
this abstract, we demonstrate a hybrid of TSE and
O-Space, developing an O-Space TSE sequence which is
much faster than single echo O-Space imaging. Various
techniques are applied to overcome the problems of
artifacts and ambiguous T2 weighting. Simulations and
experiment illustrate that the proposed method can
inherit the advantages of both TSE and O-Space.
