Real-time imaging of a moving object such as the heart uses fast imaging
with steady precession (FISP) traversing spirals in k-space. After
flipping nuclear spins in the object within a slice to be imaged, signals
are read out from the nuclear spins while applying read-out magnetic
field gradients whereby read-out signals traverse spirals in k-space.
Thereafter, the zero moment and first moment of the read-out gradients
are driven to zero quickly so that fast imaging with steady state
precession is realized without banding artifacts. Motion compensated
rewinders are applied after the read-out magnetic field gradients which
can be integral with the read-out gradients or comprise separate
compensation lobes.
