    Area of Science:

    • Medical Physics
    • Radiation Oncology
    • Biomedical Engineering

    Background:

    • Accurate patient positioning is critical for effective radiation therapy.
    • Patient movement during treatment can lead to suboptimal radiation delivery and potential harm.
    • Current verification methods may be time-consuming or resource-intensive.

    Purpose of the Study:

    • To develop and evaluate a simple, inexpensive system for detecting patient movement during radiation therapy.
    • To provide real-time alerts to radiation-therapy technologists for immediate intervention.
    • To compare the efficacy of this system with standard verification techniques.

    Main Methods:

    • Utilized existing laser localization lights from isocentric linear accelerators.
    • Integrated simple and cost-effective electronic circuitry for movement detection.

  • Implemented a system generating visual or audible signals upon detected patient displacement.

    • Main Results:

    • The developed system successfully detects patient movement during radiation therapy.
    • Alerts are generated promptly, enabling technologists to interrupt and correct patient position.
    • Verification of patient position using this method shows favorable comparison to certification radiographs.

    Conclusions:

    • This laser-based system offers a practical and economical solution for real-time patient movement detection in radiation therapy.
    • It enhances treatment accuracy and safety by facilitating timely repositioning.
    • The system provides a viable alternative or adjunct to conventional patient position verification methods.
