    A new procedure enables precise coordinate calculation from CT scans, facilitating CT-directed stereotactic surgery. This allows neurosurgeons to accurately target brain lesions using any stereotactic apparatus with GE scanners.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Radiology

    Background:

    • Stereotactic surgery requires precise localization of brain targets.
    • Computed Tomography (CT) scanning is a key imaging modality for identifying brain lesions.
    • Existing methods may have limitations in integrating CT data with stereotactic procedures.

    Purpose of the Study:

    • To describe a procedure for calculating coordinates from CT scans.
    • To enable CT-directed stereotactic surgery.
    • To facilitate accurate instrument (e.g., biopsy forceps, cannula) introduction into brain lesions.

    Main Methods:

    • Utilized CT scans from GE 8800 or GE 9800 scanners.
    • Developed a coordinate calculation procedure.
    • Integrated CT data with stereotactic apparatus.

    Main Results:

    • A method for calculating coordinates from specific CT scanner models was established.
    • The procedure allows for precise targeting of brain lesions identified on CT.
    • Facilitated the use of CT-guided stereotactic surgery.

    Conclusions:

    • The described procedure enables CT-directed stereotactic neurosurgery.
    • Neurosurgeons can perform accurate interventions on brain lesions using GE scanners and any stereotactic device.
    • Enhances the utility of CT imaging in surgical planning and execution.
