Devices and method for magnetic resonance guided rotation of an object positioned within a bore of a magnetic resonance device are provided. The devices and method involve obtaining magnetic resonance measurements and rotating the object based on at least one magnetic resonance measurement. Systems comprise at least one irradiation unit configured to deliver radiation to a specified target in a treated object, and a magnetic resonance device (MRD) configured to derive magnetic resonance images of the treated object, the MRD comprising a positioning unit configured to position the treated object at at least two positions, wherein the MRD is configured to detect at least two locations of the specified target at the corresponding at least two positions of the treated object, wherein the system is further configured to adjust the at least one irradiation unit to deliver radiation to the detected at least two locations.
