Synopsis

This study investigated the long-term stability of GIRF within an eight-month period, together with the benefits of an optimized GIRF acquisition protocol. These studies provide insight into mechanisms of image quality degrading and potentially lead to improved image quality control, generalizable to arbitrary imaging sequences.
