Abstract
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. 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, an octant navigator portion which includes at least one octant navigator, and a spoiler portion provided for reducing a signal magnitude of the scanning sequence. The octant 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.
