An automated landmark system, positioning anatomy of interest at magnet isocenter, can simplify a MR exam. It can also ensure automatic scan plane prescription algorithms are provided with the correct input. A system is presented that localizes the imaging coil along the Superior/Inferior axis, enabling automatic translation of coil center from home position to magnet isocenter. Once the anatomy of interest is at isocenter, scout images are acquired and processed, localizing the coil relative to the patient, and enabling computation of the scan volume center. This dual localization permits imaging with optimal positioning, while completely eliminating the manual landmark.
