摘要： Certain embodiments of the present invention provide a system and method for temporally aligning a plurality of cardiac image sequences. The method includes performing a locally linear embedding algorithm on a first set of cardiac image sequences and on a second set of cardiac image sequences. A graphical representation is created for the first set of cardiac image sequences and the second set of cardiac image sequences. A determination is made whether the first set of cardiac image sequences and the second set of cardiac image sequences were generated from a similar point of view. If a similar point of view is found, the first graphical representation and the second graphical representation are aligned using a minimization function. If a similar point of view is not found, the graphs are aligned with a template and then aligned with each other using the minimization function.

摘要： Certain embodiments of the present invention provide systems and methods for detecting septal defects. In an embodiment, the method may include acquiring gated MRI data and heart atlas data. A registration of the gated MRI data and the heart atlas data may be performed as well as a flow-balance measurement. An atrial septal detection and ventricular septal detection may be performed, as well as a septal measurement. A diagnostic report may be generated detailing the location and properties of the septal defects. A physician may utilize the diagnostic report for surgery planning. After surgery, the diagnostic report may be compared with a post-surgery diagnostic report to determine the success of the surgery.
