    Area of Science:

    • Urology
    • Medical Physics
    • Biomedical Engineering

    Background:

    • Efficient extracorporeal shock wave lithotripsy (ESWL) relies on precise stone localization.
    • Operator uncertainty with Dornier HM-3 control panel axes (x, y, z) can lead to prolonged positioning times and increased fluoroscopy.
    • Optimizing ESWL control usage may reduce procedure duration and patient radiation exposure.

    Purpose of the Study:

    • To provide a didactic aid for understanding Dornier HM-3 control panel maneuvers.
    • To elucidate the angles and relative velocities associated with simple and complex stone positioning movements.
    • To enhance operator proficiency in extracorporeal shock wave lithotripsy stone localization.

    Main Methods:

    • Analysis of control panel inputs for the Dornier HM-3 lithotripter.
