Lung Navigation Display with Dynamic Image Selection by Instrument Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical imaging systems face challenges in dynamically displaying accurate and appropriate information based on the position and status of navigation instruments, leading to potential risks and increased clinician training needs.
Innovation Solution
A medical image display apparatus and system that integrates a network interface, processor, memory, and display to dynamically select and update medical images based on positional and status information from a navigation instrument, including 2D and 3D maps, live and virtual bronchoscopic video, and other imaging modalities, automatically adjusting display settings to enhance clarity and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical imaging systems display static and fixed information, then the system is simple to operate, but the information may become inaccurate or inappropriate as the navigation instrument moves and procedural conditions change
Solution Approach 1:
The display system dynamically updates medical images and information based on the real-time position and status of the navigation instrument. The system automatically adjusts which images are displayed, their orientation, and their content according to the instrument's location within the patient's body, ensuring the information remains accurate and relevant throughout the procedure.
Solution Approach 2:
The system continuously receives feedback from position sensors tracking the navigation instrument's location and uses this information to automatically update the displayed medical images. This closed-loop feedback mechanism ensures the display reflects the current procedural state without requiring manual intervention.
2Loss of information
If the display system automatically adjusts based on navigation instrument position and status, then information accuracy improves, but the processing and control complexity increases
Solution Approach 1:
The display system is designed to handle multiple functions through a unified automatic adjustment mechanism. It simultaneously manages image selection, orientation, scaling, and content updates based on a single integrated input from the navigation instrument's position sensors, reducing the need for separate control systems for each function.
Solution Approach 2:
The system performs self-adjustment by automatically selecting and updating appropriate medical images based on navigation instrument position and procedural status without requiring manual intervention. The display adapts itself to the current procedural context, reducing the burden on clinicians to manually configure display settings.
3Loss of information
If multiple medical images and imaging modalities are displayed simultaneously, then comprehensive information is provided, but the display becomes cluttered and harder to interpret
Solution Approach 1:
The display system presents different types of medical information in optimized formats tailored to their specific purposes. Critical navigation-related images are displayed with prominent positioning and appropriate scaling, while supplementary information is organized in less prominent areas. Each region of the display is optimized for its specific function, improving overall interpretability.
Solution Approach 2:
The display is divided into multiple independent regions or panels, each showing specific types of medical images or information. This segmentation allows clinicians to view comprehensive information across multiple modalities while maintaining clear visual separation, reducing clutter and improving readability.
4Productivity
If the system requires manual adjustment of display settings, then the system is simpler to control, but more training is needed and procedural efficiency decreases
Solution Approach 1:
The display system automatically configures and adjusts all display settings based on real-time inputs from the navigation instrument's position sensors and procedural status. This self-service capability eliminates the need for manual adjustment during procedures, allowing clinicians to focus on the surgical task rather than display configuration, thereby improving both ease of use and procedural efficiency.

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.
