    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Surgical Navigation

    Background:

    • Accurate localization of intracranial lesions is critical for effective surgical intervention and treatment planning.
    • Existing localization methods may have limitations in precision or applicability across different imaging modalities.
    • The need for integrated pre- and intraoperative guidance systems is paramount in neurosurgery.

    Purpose of the Study:

    • To describe a new computed tomography (CT) localization system designed for intracranial lesions.
    • To evaluate its utility in pre- and intraoperative guidance.
    • To explore its potential applications in stereotactic surgery and radiotherapy planning.

    Main Methods:

    • Development of a novel CT localization system comprising an acrylic plate with air grooves for CT examinations.
    • Utilization of a duplicate plate with wires for scout radiography, enabling cross-modal localization.
    • Integration of the system for pre- and intraoperative guidance in neurosurgical procedures.

    Main Results:

    • The described system provides a method for precise localization of intracranial targets.
    • The dual-plate design facilitates seamless transition between CT and scout radiography.
    • The system demonstrates versatility for application in stereotactic surgery and radiotherapy planning.

    Conclusions:

    • The new CT localization system offers a valuable tool for enhancing the precision of intracranial lesion targeting.
    • Its adaptability for pre- and intraoperative use, as well as for stereotactic surgery and radiotherapy, underscores its broad clinical potential.
    • This system represents an advancement in neuronavigation and surgical planning technologies.
