Area of Science:

  • Medical Informatics
  • Computational Anatomy
  • Surgical Technology

Background:

  • Computer-assisted surgery applications, including navigation, robotics, and simulation, require robust formal models.
  • These models must consistently represent anatomical part-whole relationships (mereology) and neighborhood (topology) for automated spatial reasoning.
  • Existing approaches may lack the necessary logical foundation for complex anatomical representations.

Purpose of the Study:

  • To investigate the suitability of mereotopological theories for providing a logical background for anatomical models in computer-assisted surgery.
  • To identify limitations in current mereotopological theories concerning anatomical data representation.
  • To guide the development of more effective spatial reasoning capabilities in surgical technologies.

Main Methods:

  • Review and analysis of existing mereotopological theories.
  • Evaluation of their applicability to formalizing anatomical part-whole and neighborhood relationships.
  • Assessment of the logical consistency and spatial expressiveness of these theories.

Main Results:

  • Mereotopological theories offer a potential logical framework for anatomical modeling.
  • Current theories face challenges in consistently representing the complex spatial nature of anatomical structures.
  • A need exists for a more spatially motivated classification of anatomical structures.

Conclusions:

  • Mereotopological theories can serve as a foundation for anatomical modeling in computer-assisted surgery.
  • Further development is required, focusing on a spatially informed anatomical classification.
  • This will enable more consistent and logically sound mereotopological modeling for surgical applications.
