Method for reducing image artifacts caused by patient motion during MR imaging |
摘要 |
An MRI system acquires MRA data from two overlapping thin slabs using a 3DTOF pulse sequence. Motion artifacts are reduced by using a reverse centric phase encode order during the first thin slab acquisition and a centric phase encode order during the second thin slab acquisition. Patient movement is reduced by producing a uniform sound with gradient pulse sequences during the interval between thin slab acquisitions and during a preparation period prior to the first thin slab acquisition.
