Definition of anatomically consistent and accurate scan volume orientations is a prerequisite for diagnostic reliability both for manual and automated MRI scan planning. The proposed method automatically recognizes major structures of the human heart from unseen breathing-gated, ECG-triggered, isotropic 3D MRI volumes, and calculates anatomical landmarks of these structures. Based on a set of training samples, for which automatically calculated landmarks and user-defined examples of scan volume orientations are available, the proposed method infers corresponding scan volume orientations for unseen images. Performance of the proposed recognition/planning method is compared to manually defined scan volume orientation for a four chamber view.
