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.
Claims20
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 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 stored ROI descriptive data 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 patient during positioning and/or treatment of said patient in the treatment room.
System according to claim 8, wherein said ROI labelled 3D surface is read into a quality module of said system, wherein said quality module is configured to estimate one or more geometric measurements of the 3D data in said ROI labelled 3D surface and to compare said estimated geometric measurements with one or more set thresholds.
