Abstract :
Potential field algorithms often used in path finding applications on a 2D plane are expanded onto a 3D map trajectories for navigation planning of a microdevice designed to be propelled through the cardiovascular system using magnetic gradients generated by a clinical MRI system. This system assembles a 3D reconstruction of a cardiovascular system through magnetic resonance angiography images. The method also allows the extraction of the physiological properties of the given network
