CORRECTED MULTIPLE-SLICE MAGNETIC RESONANCE IMAGING |
摘要 |
The invention provides for a magnetic resonance imaging system (100) for acquiring magnetic resonance data (142, 148, 158) with a pulse sequence (140) for multiple slice acquisition performed over multiple repetition cycles. The magnetic resonance imaging system further comprises a processor (540) for controlling the magnetic resonance imaging system. The execution of the instructions cause the processor to: acquire (200) a first slice group (142) of the magnetic resonance data during a first repetition cycle; extract (202) first central k-space data (144) from the first slice group; reconstruct (204) first navigator data (146) using the first central k-space data. Execution of the instructions causes the processor to repeatedly: acquire (206) a subsequent slice group (148) of the magnetic resonance data during a subsequent repetition cycle; extract (208) subsequent central k-space data (150) from the subsequent slice group; reconstruct (210) subsequent navigator data (152) using the subsequent central k-space data; determining (212) a mapping (154) from the first navigator data to the subsequent navigator data; and correct (214) the acquisition of a next slice group of the magnetic resonance data using the mapping. |
