A method and system of correcting for a motion of an object are provided. In
these
system and method, the navigator data and map data are first obtained for the object.
Then, the navigator data is compared with the map data to generate comparison data.
Thereafter, a translation and/or a rotation of the object is corrected in real
time as a function of the comparison data. The navigator can be preferably an octant
navigator and/or a clover leaf navigator. In one exemplary embodiment, a scanning
sequence can be used to determine a position of the object. This scanning sequence
may include a signal portion which includes at least one radio frequency signal,
a navigator portion which includes at least one octant navigator or one clover
leaf navigator, and a spoiler portion provided for reducing a signal magnitude
of the scanning sequence. The navigator is provided for allowing a measurement
of at least one of the rotation and translation of the object. The navigator portion
is advantageously provided between the signal portion and the spoiler portion.
