MAGNETIC RESONANCE METHOD GENERATING NAVIGATOR PULSE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance method generating an emphasized navigator pulse. SOLUTION: In this magnetic resonance method, the navigator pulse is generated by use of at least one RF pulse and at least two gradient magnetic fields having gradients severally spreading in time and space such that the navigator pulse excites nuclear magnetization within a spatially restricted volume, and at least one MR signal is received from the volume with a further gradient magnetic field and is estimated. Temporal fluctuation is applied to the gradient magnetic field such that at least two MR signals corresponding to the excitation in a k-space are generated along mutually offset orbits, and the MR signals are composed.
