To
address cardiac motion, data acquisition is limited to quiescent periods of
the cardiac cycle necessitating a segmented method. However, respiratory
motion resulting from failed breath holding remains an issue. If a subject
fails to maintain a consistent breath hold throughout the entire scan the
acquired K-space data is not consistent across segments and this can result
in motion artifacts. A new scheme of segment arrangement is proposed in this
context. Phantom and human studies were evaluated with the two schemes.
