Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If preoperative images are used to provide anatomical context, then anatomical information is available, but the images do not reflect intraoperative changes leading to misalignment
Solution Approach 1:
The system dynamically updates the anatomical model during the procedure by integrating real-time endoluminal imaging data with preoperative images. This allows the virtual anatomical representation to adapt to intraoperative changes such as tissue deformation, respiratory motion, and surgical interventions, maintaining alignment precision throughout the procedure.
Solution Approach 2:
The system employs feedback mechanisms where real-time endoluminal images are continuously compared with the virtual anatomical model. Discrepancies detected through image registration algorithms trigger automatic updates to the anatomical model, creating a closed-loop system that maintains accuracy despite anatomical changes.
2Ease of operation
If mental mapping is used to align live endoscopic video with preoperative images, then some spatial understanding is achieved, but precision is insufficient for medical procedures
Solution Approach 1:
The system creates a detailed virtual copy of the patient's anatomy from preoperative imaging data. This digital twin is then overlaid with augmented reality visualization, providing both intuitive spatial understanding and precise localization. The virtual model serves as an accurate reference that practitioners can directly compare with live endoscopic views.
3Measurement precision
If endoscope tracking methods are used, then external localization is provided, but internal anatomy cannot be visualized
Solution Approach 1:
The system merges endoscope tracking data with virtual anatomical model rendering. Tracking information provides precise localization of the endoscope position and orientation, while the virtual anatomical model fills in the internal anatomy that cannot be directly visualized. The augmented reality display combines both data streams to provide comprehensive navigation information.
4Loss of information
If practitioners constantly reference screens to integrate spatial data, then complete information is available, but cognitive load increases during the procedure
Solution Approach 1:
The system transitions spatial data from two-dimensional screens to three-dimensional augmented reality visualization. The virtual anatomical model is rendered in 3D space and overlaid with the live endoscopic view, allowing practitioners to perceive spatial relationships more naturally. This dimensional enhancement reduces the cognitive effort required to integrate multiple data sources.

AI summary
A system for image-guided intervention of a patient is provided. The system can include an endoluminal probe, a tracking system, a display system, and a registration system. The endoluminal probe can be configured to acquire a real-time image of an internal site within the patient. The tracking system can be configured to track a position and an orientation of the endoluminal probe. The display system can be configured to display the real-time image acquired by the endoluminal probe. The registration system can be configured to register the real-time image from the endoluminal probe with a preoperative image of the internal site. The display system can overlay the registered real-time image from the endoluminal probe with the preoperative image to assist in navigation and intervention at the internal site.
