Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Biomedical Engineering

Background:

  • Surface-guided radiation therapy (SGRT) systems are crucial for patient setup and motion monitoring in radiation oncology.
  • Commercial SGRT systems are expensive, limiting their accessibility in resource-limited healthcare settings globally.
  • There is a need for cost-effective SGRT solutions to improve treatment precision and patient safety worldwide.

Purpose of the Study:

  • To develop and validate a smartphone-based application utilizing LiDAR camera technology for SGRT.
  • To create an affordable SGRT solution suitable for low-resource clinics.
  • To demonstrate the feasibility and accuracy of the smartphone SGRT application compared to commercial systems.

Main Methods:

  • An iOS application was developed using Swift and ARKit on an iPhone 13 Pro with a LiDAR camera.
  • The application features real-time visualization of depth feeds, region-of-interest selection, and motion trace analysis.
  • Validation involved testing depth accuracy with angled surfaces and comparing motion measurements against commercial SGRT systems using phantoms and volunteers across three institutions.

Main Results:

  • The smartphone SGRT application demonstrated excellent agreement with commercial systems for depth (r=1.000) and angle (r=1.000) measurements.
  • Motion traces from the application showed significant correlation with phantom motion (r=0.97-0.99) and healthy volunteer motion (r=0.98-0.99) across all tested institutions.
  • Low bias values (e.g., -0.07±0.24 cm for depth) indicate high measurement precision.

Conclusions:

  • The developed smartphone application provides a viable, low-cost platform for implementing surface-guided radiation therapy.
  • This technology has the potential to significantly enhance access to motion-guided radiation therapy in underserved regions.
  • The findings support the use of readily available smartphone technology for advanced cancer treatment monitoring.
