Purpose: An optical tracking and positioning system (OTPS) was developed to validate the software-driven isocentric (SDI) approach to control the six-degrees-of-freedom movement of a robotic couch.

Methods: The SDI approach to movements rotating around a predefined isocenter, referred to as a GeoIso, instead of a mechanical pivot point was developed by the robot automation industry. With robotic couch-sag corrections for weight load in a traditional SDI approach, movements could be accurately executed for a GeoIso located within a 500 mm cubic volume on the couch for treatments.

Article Synopsis
  • Proton therapy is effective for large, shallow areas but requires multiple matched fields due to beam production limits, making accurate dose planning essential.
  • Shifting the patient for field matching necessitates precise positioning within 1-2 millimeters for effective treatment delivery.
  • A study using an innovative robotic patient positioner system (RPPS) showed that dosimetric accuracy between treatment planning calculations and measurements was highly consistent, supporting the efficiency of RPPS in proton field matching.
