Abstract
A system, method, software arrangement and computer-accessible medium for correcting for a motion of an object are provided. In this system, method, software arrangement and computer-accessible medium, the navigator data and map data can be obtained for the object. Then, the navigator data is compared with the map 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 a clover leaf navigator. In one exemplary embodiment, a scanning sequence can be used to determine a position of the object. For example, this scanning sequence may include a signal portion which includes at least one radio frequency signal, a navigator portion which includes at least 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 the rotation and/or the translation of the object. The measurement can be adjusted by correcting for phase encoding effects, shimming errors, and B0 drifts. A feedback control system may be provided to repeatedly correct the measurement of the…
