    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Surgical Technology

    Background:

    • Stereotactic surgery is often described as a blind procedure.
    • Intraoperative visualization is crucial for improving surgical safety and accuracy.

    Purpose of the Study:

    • To develop and clinically apply an apparatus for intraoperative CT imaging during stereotactic surgery.
    • To enhance the safety and reliability of stereotactic procedures by providing real-time environmental and target point confirmation.

    Main Methods:

    • Integration of a whole-body CT scanner with a stereotactic system.
    • Clinical application of the developed apparatus for intraoperative imaging.
    • Acquisition of CT images within approximately 9 seconds.

    Main Results:

    • The apparatus successfully provides intraoperative CT images.
    • The system allows for confirmation of target point location and assessment of the intraoperative environment.
    • Procedures such as evacuation of deep-seated intracerebral hematomas, brain abscess treatment, and brain tumor biopsy or brachytherapy were performed with safety and reliability.

    Conclusions:

    • Intraoperative CT scanning significantly improves the safety and reliability of stereotactic neurosurgery.
    • This technology transforms traditionally blind procedures into visualized interventions.
    • The minimally invasive approach under local anesthesia facilitates complex deep-seated brain interventions.
