Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If medical imaging systems display static information, then the system complexity is low, but the information accuracy and appropriateness for dynamic navigation procedures deteriorates
Solution Approach 1:
The display system dynamically adjusts the type and content of medical images shown based on the real-time position and status of the navigation instrument. The system transitions from static to dynamic display modes, automatically selecting appropriate image types (axial, coronal, sagittal, 3D maps, etc.) according to the procedural phase and instrument location, thereby improving information accuracy without requiring manual intervention.
Solution Approach 2:
The system continuously receives position information from the navigation instrument and uses this feedback to automatically adjust the displayed medical images. The display updates in real-time based on instrument status, ensuring that clinicians always see relevant information appropriate to the current procedural stage and instrument location.
2Ease of operation
If the system automatically adjusts displayed information based on navigation instrument position and status, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The display system performs automatic adjustments without requiring manual input from clinicians. It autonomously determines the appropriate medical images to display based on navigation instrument position and status information, effectively making the system self-adjusting and reducing the operational burden on users.
Solution Approach 2:
The system integrates multiple functions into a single automated display mechanism that handles various navigation modes, instrument positions, and image types. This multi-functional approach consolidates what would otherwise require multiple separate controls and adjustments, improving ease of operation while managing complexity through integration.
3Loss of information
If multiple types of medical images are displayed simultaneously, then the information completeness improves, but the ease of interpreting the displayed information deteriorates
Solution Approach 1:
The system displays different types of medical images (axial, coronal, sagittal, 3D maps, pathway plans, target locations) selectively based on the specific navigational context and procedural phase. Rather than showing all image types simultaneously, the system provides locally optimized information appropriate to each situation, maintaining completeness while improving interpretability.
4Measurement precision
If the display updates frequently to track navigation instrument position, then the information accuracy improves, but the productivity in terms of processing speed and resource usage deteriorates
Solution Approach 1:
The system updates displayed medical images at appropriate intervals based on changes in navigation instrument position and status. Rather than continuous updating, the system employs periodic refreshes triggered by significant position changes or status transitions, maintaining synchronization accuracy while reducing unnecessary processing overhead.

AI summary
A medical image display apparatus for displaying medical images of a lung on a screen includes a network interface receiving positional information of a navigation instrument from a position sensor of the navigation instrument, a video stream from an optical sensor of the navigation instrument, and medical images from an imaging device, a memory storing a plurality of medical images and instructions, a processor executing the instructions, and a display dynamically displaying images on the screen. The instructions, when executed by the processor, cause the medical image display apparatus to determine whether status information indicates a pathway reviewing mode, a target management mode, or a navigation mode. The instructions, when executed by the processor, further cause the display to dynamically select and update images, which are displayed on the screen, among the plurality of medical images based on the positional information of the navigation instrument and status information.
