Dynamic Image Assignment for Surgical Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image-guided surgery systems with multiple display devices lack the ability to dynamically adjust and synchronize images based on the relative position and viewer identity, leading to suboptimal information dissemination and potential distractions from reflections.
Innovation Solution
A system comprising a position determinator and image generator that calculates the relative position of display devices and adjusts images accordingly, allowing for independent or synchronized image display on each device, and incorporates viewer detection to tailor content based on the viewer's identity, while using sensors and cameras to minimize reflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display devices are used to provide comprehensive surgical information, then information completeness is improved, but information delivery accuracy deteriorates because the system cannot determine which viewer should see which information
Solution Approach 1:
The system dynamically adjusts image display assignments based on real-time detection of viewer identity and position. The image generator receives viewer information from the viewer detector and position data from the position determinator, then dynamically determines which images to display on which devices, ensuring each viewer receives appropriate information for their role and location in the surgical procedure
Solution Approach 2:
The system implements a feedback loop where the viewer detector continuously identifies viewers and their positions, feeds this information to the image generator, which then adjusts display assignments accordingly. This closed-loop feedback mechanism ensures that information delivery remains accurate despite changes in viewer configuration during surgery
2Ease of operation
If the system displays all surgical information on all display devices, then information accessibility is improved, but viewer distraction increases due to irrelevant information and reflections
Solution Approach 1:
The system applies local quality by customizing the display content for each display device based on the specific viewer's identity, role, and position. Rather than uniform display across all devices, each screen presents a tailored subset of information relevant to that particular viewer, reducing distraction while maintaining accessibility
Solution Approach 2:
The system extracts and removes irrelevant information from each viewer's display based on their role and position. The image generator filters out information that is not pertinent to the detected viewer, displaying only the necessary subset of surgical images and data, thereby eliminating distracting elements while preserving essential information access
3Device complexity
If fixed image assignments are made to display devices, then system complexity is reduced, but adaptability deteriorates when viewer positions or identities change during surgery
Solution Approach 1:
The system employs dynamic image assignment where the image generator continuously receives updated viewer detection data and position information, then automatically reassigns images to display devices in real-time. This dynamic adaptation allows the system to respond to changing surgical team configurations without requiring manual reconfiguration or increasing operational complexity
Solution Approach 2:
The system performs self-service by automatically detecting viewer changes and autonomously adjusting display assignments without requiring manual intervention from the surgical team. The viewer detector and image generator work together to self-adapt the display configuration, maintaining simplicity of operation while achieving high adaptability to changing conditions
