1. A therapeutic system comprising: a therapy transducer configured to direct a therapeutic action to a target; a magnetic resonance (MR) imager configured to generate image information of a therapy region that includes the target; a motion analysis processor configured to derive a motion vector field from the image information of the therapy region; and a controller configured to control the therapy transducer based on the motion vector field, wherein the MR imager is configured to acquire MR signals from the therapy region, and to derive the image information from the magnetic resonance signals; and wherein the controller includes a thermography unit configured to derive a temperature distribution of the therapy region from the magnetic resonance signals, taking the motion vector field into account.
