Abstract
A system and methods are provided for controlling interventional devices using magnetic resonance imaging ('MRI') guidance. In some aspects, the method includes arranging a pivoting guide about a subject's anatomy that is configured to direct an interventional device toward a selected target point within the subject's anatomy, generating, using an MRI system, MR data associated with markers placed on the pivoting guide, and determining a vector defining an orientation of the pivoting guide from locations for the markers identified using the MR data. The method also includes orienting the pivoting guide in multiple directions to determine multiple vectors, and identifying a pivot point for the pivoting guide using the determined vectors. The method further includes determining a trajectory for the interventional device using the identified pivot point and the selected target point, and controlling the interventional device along the determined trajectory.
