Research Abstract

In this study, a new fast MRI pulse sequence ‘Bunched Phase Encoding (BPE)' has been further investigated. New techniques have been developed to readily perform BPE scanning and improve quality of the images. Furthermore, a new reconstruction method in spiral imaging has been developed. In this method, while data are under-sampled, no apparent aliasing artifacts can be observed in the images.
