技術摘要 / Our Technology: |
一種同時取得多截面/區塊磁共振訊號之控制方法、成像方法及系統,本發明之控制方法係對一受測物進行包含下述步驟:(a)施加一個或多個載有至少二頻率之射頻脈衝與一截面/區塊激發梯度磁場,使該受測物對應各該頻率的至少二截面/區塊被激發;(b)施加一空間編碼梯度磁場;及(c)施加至少一能使各該截面/區塊彼此區隔之截面/區塊區隔梯度磁場。藉由本發明方法取得之資料能同時重組多截面/區塊之磁共振影像且相容於現有系統硬體。
Provided is a method for simultaneously acquiring magnetic resonance slices/slabs of a subject. The method comprises steps as follows. First, apply one or more than one RF pulse, which carries at least two frequency components, and a slice/slab selection magnetic field gradient so that at least two slices/slabs of the subject respectively corresponding to the at least two frequency components are excited simultaneously. Second, apply a spatial encoding magnetic field gradient. Third, apply a slice/slab separation magnetic field gradient so as to separate the at least two slices/slabs. The method according to the present invention can be used to acquire data for simultaneously reconstructing multiple slices/slabs. The method is compatible with existing MRI systems.
