    Area of Science:

    • Neurosurgery
    • Radiation Oncology
    • Medical Device Engineering

    Background:

    • The evolution of Gamma Knife technology aimed to improve stereotactic radiosurgery delivery.
    • Early Gamma Knife models utilized interchangeable helmets with varying collimator sizes, enhancing treatment flexibility but posing logistical challenges.

    Observation:

    • The U model involved complex hydraulic patient positioning.
    • The B model simplified patient movement but retained the need for manual helmet changes.
    • The C model introduced automated patient positioning but still required helmet swaps for different collimator sizes.

    Findings:

    • The Perfexion Gamma Knife model eliminated the need for helmets entirely.
    • This redesign allows for complete patient treatment after initial positioning, irrespective of collimator size requirements.
