Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If intra-operative image data is integrated with navigation tools, then navigation precision is improved, but system complexity increases
Solution Approach 1:
The patent merges intra-operative imaging capabilities directly into the navigation system by integrating the imaging system with the navigation tool. This allows real-time image acquisition and processing within the navigation framework, improving navigation precision while managing system complexity through unified architecture.
Solution Approach 2:
The navigation system is designed to perform multiple functions: navigation guidance, real-time imaging, image processing, and anatomical target identification. This multi-functional approach consolidates what would otherwise require separate systems, addressing the precision improvement while controlling overall system complexity.
2Measurement precision
If real-time image processing is performed, then navigation accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing image data in real-time during acquisition. This allows the navigation system to access pre-processed image information quickly during navigation, improving navigation accuracy without adding significant processing delays during critical navigation moments.
Solution Approach 2:
The imaging and processing operations run continuously during the procedure, maintaining a constant stream of processed image data available for navigation. This continuous processing eliminates batch processing delays and ensures navigation accuracy is maintained throughout the procedure without intermittent time losses.
3Measurement precision
If instrument shape data is registered to image data, then anatomical target identification is improved, but registration complexity increases
Solution Approach 1:
The system performs self-service by automatically registering instrument shape data to image data using the imaging system's own resources and algorithms. This automated self-registration reduces the need for complex manual registration procedures and external tools, improving anatomical target identification while managing registration complexity through self-contained processing.

AI summary
A system comprises a processor, a display, and a memory having computer readable instructions stored thereon that, when executed by the processor, cause the system to receive intra-operative three-dimensional image data from an imaging system. A portion of the intra-operative three-dimensional image data corresponds to an instrument disposed in a patient anatomy. The computer readable instructions, when executed by the processor, further cause the system to generate two-dimensional projection image data from the intra-operative three-dimensional image data, display the two-dimensional projection image data on the display, and identify, within the two-dimensional projection image data, a three-dimensional location of a portion of the instrument.
