System, method, software arrangement and computer-accessible medium for providing real-time motion correction by utilizing clover leaf navigators
First Claim
1. A method of correcting or compensating for a motion of an object during a magnetic resonating imaging (“
- MRI”
) scan of the object, comprising the steps of;
obtaining first data for the object, the first data including data defining a navigator and a path of the navigator;
obtaining second data for the object, the second data defining a map of the object;
determining whether at least one of a correction or a compensation of at least one of a translation or a rotation is to take place, wherein the correction or the compensation is performed based on the first data, the second data and deviations of at least one of the first data or the second data.

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 rotation and translation of the object. The navigator portion can advantageously be provided between the signal portion and the spoiler portion. The system, method, software arrangement and computer-accessible medium may be implemented when multiple coils are present.
