Abstract: Embodiments of systems, methods, and non-transitory computer readable media for automatic landmarking are presented. A coil including at least one marker is placed on a desired region on interest (ROI) of a subject. Further, a detector detects a position of the marker while translating the subject from a home position in an imaging system into a bore of a magnet in the imaging system.

Further, the positioning unit determines a distance between the detected marker position and a homogenous position of the magnet based at least on the detected marker position. The positioning unit then controls movement of the subject over the determined distance to the homogenous magnet position for automatically landmarking the desired ROI.
