Abstract
The present disclosure relates to a patient motion tracking system for automatic generation of a region of interest on a 3D surface of a patient positioned in a radiotherapy treatment room. More particularly, the disclosure relates to an assistive approach of a motion tracking system, by which a region of interest (ROI) is automatically generated on a generated 3D surface of the patient. Furthermore, a method for automatically generating a ROI on the 3D surface of the patient is described. In particular, all the embodiments refer to systems integrating methods for automatic ROI generation in a radiotherapy treatment setup.
Claims3
A patient motion tracking system for automatic generation of a region of interest on a 3D surface of a patient positioned in a radiotherapy treatment room, the system comprising:
- a memory comprising stored region of interest (ROI) descriptive data;
- a training module, including at least one processor, configured to generate a template surface and template ROI from the stored ROI descriptive data;
- a 3D surface generation processor configured to
- utilize an input surface, and
- generate a 3D surface from said input surface, wherein the 3D surface comprises at least a target area of the input surface;
- a ROI generation processor configured to utilize said template surface and template ROI generated by said training module and said 3D surface to output a ROI labelled 3D surface to a display and a motion tracking module,
- wherein said ROI labelled 3D surface is utilized by the motion tracking module to track motion of a patient during positioning and/or treatment of said patient in the treatment room.
