The present disclosure relates to a patient motion tracking system for automatic generation of a region of interest. The system comprises: a memory comprising stored region of interest, ROI, descriptive data; a 3D surface generating processor configured to utilize an input surface and generate a 3D surface from the input surface, wherein the 3D surface comprises at least a target area of the inputsurface; an ROI generation processor configured to output an ROI-tagged 3D surface to a display and motion tracking module using the stored ROI descriptive data and the 3D surface, wherein the ROI-tagged 3D surface is used by the motion tracking module to track motion of a patient during localization and/or treatment of the patient in a treatment room.
