Diaphragmatic one-dimensional navigation (NAV) is the conventional approach for CMRA respiratory motion compensation. This method has limitations such as the cumbersomeness of setting NAV and giving stresses to patients by wrapping the compression band around the chest/abdomen for minimizing respiratory artifacts. Image-based 2D navigator (iNAV) can solve this limitation because it directly corrects the translational movement of the heart in two directions (R-L and F-H) by using 2D real-time imaging. We investigate the feasibility of iNAV with loosely wrapped abdominal compression band compared to the conventional NAV approach.
