技術說明

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。 A method for simultaneously acquiring magnetic resonance slices/slabs, which contains several steps applied to the subject: (a) a radio-frequency pulse with at least two different carrier frequencies, simultaneously exciting at least two slices/slabs at different positions of said subject; (b) a series of spatial encoding magnetic gradients; and (c) a magnetic gradient to separate the simultaneously excited slices/slabs. The data acquired by this method can be used to construct a set of several slices/slabs in a single acquisition. This method is compatible to all existing MRI systems.
