Abstract

In this paper, the application of simultaneous multi-slice excitation and acquisition technique in T₁-Weighted magnetic resonance imaging (MRI) at low field scanner was investigated. The solutions for simultaneous multi-slice excitation with different thickness, and reduction of long T₁ effects on the separation of overlapped slices were discussed. Computer simulations and experimental results show that these methods can effectively solve the limitation of slice number within a relatively short repetition time in low-field T₁-weighted MRI.
