To enhance the topological maps generated by ColonSLAM, leveraging long-term relationships between entry and withdrawal phases, as well as multiple explorations of the same patient, can be pivotal. By establishing connections between these phases, the system can create a more comprehensive representation of the colon's anatomy and the procedural journey. This can be achieved through the following strategies:
Temporal Mapping: Implementing a temporal mapping framework that records the sequence of entry and withdrawal phases can help in identifying recurring patterns and anatomical landmarks. By associating specific submaps from the entry phase with their corresponding withdrawal phase, the system can create a more cohesive topological graph that reflects the entire exploration process.
Patient-Specific Mapping: Each patient's unique anatomy and history can be integrated into the mapping process. By storing and analyzing data from previous colonoscopies, ColonSLAM can recognize familiar patterns and anatomical structures, allowing for more accurate localization and mapping during subsequent procedures. This could involve using machine learning techniques to predict the likelihood of encountering specific regions based on past explorations.
Enhanced Covisibility Detection: By utilizing advanced visual place recognition techniques, the system can improve its ability to detect covisible submaps across different exploration sessions. This could involve training the localization network to recognize not only immediate covisible areas but also those that may have been observed in previous sessions, thus enriching the topological graph with historical data.
Integration of Clinical Insights: Incorporating clinical insights, such as findings from previous colonoscopies or known disease patterns, can guide the mapping process. For instance, if a patient has a history of polyps in a specific region, the system can prioritize mapping and exploring that area more thoroughly during the current procedure.
By implementing these strategies, ColonSLAM can create a more robust and informative topological map that not only reflects the current exploration but also builds upon the patient's medical history and previous procedures.
