    A new software program, Seapit, precisely calculates intracranial target coordinates using stereotactic computed tomography (CT). This advanced method enhances accuracy and safety in stereotactic neurosurgery procedures.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Computer Science

    Background:

    • Stereotactic surgery requires precise localization of intracranial targets.
    • Computed tomography (CT) is a key imaging modality for stereotactic procedures.
    • Accurate coordinate calculation is crucial for surgical precision and patient safety.

    Purpose of the Study:

    • To develop and evaluate a computer software program (Seapit) for precise determination of intracranial targets.
    • To integrate Seapit with a GE 8800 CT scanner for enhanced stereotactic surgery planning.
    • To improve the accuracy and safety of stereotactic interventions through advanced software solutions.

    Main Methods:

    • Development of the Seapit software for millimetre-precise calculation and display of rectilinear coordinates from axial CT images.
