Hexagonal Undersampling for Faster MR Imaging near Metallic Implants
2015
Purpose
Slice encoding for metal artifact correction (SEMAC) acquires a 3D image of each excited slice with view-angle tilting to reduce slice and readout direction artifacts respectively, but requires additional imaging time. The purpose of this study is to provide a technique for faster imaging around metallic implants by undersampling k-space.
