    Area of Science:

    • Medical Imaging
    • Computational Topology
    • Digital Geometry

    Background:

    • The spherical homeomorphism conjecture is crucial for correcting the topology of human cerebral cortex MRIs.
    • Previous work by Shattuck and Leahy (2001) established a theorem for surfaces.

    Discussion:

    • This study formulates and proves a generalized spherical homeomorphism theorem.
    • The theorem is validated for all digital images under the (26,6)-connectivity rule.
    • A canonical image-thickening technique is employed.

    Key Insights:

    • A novel spherical homeomorphism theorem applicable to all digital images is presented.
    • The (26,6)-connectivity rule is integral to the theorem's validity.
    • This work enhances the topological accuracy of medical image processing.

    Outlook:

    • Potential applications in advanced neuroimaging analysis.
    • Further exploration of connectivity rules in digital topology.
    • Foundation for improved algorithms in medical image correction.
