Adaptive Intraluminal Image Scaling for Vessel Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intraluminal imaging systems face challenges in displaying intraluminal images with consistent scale, particularly when imaging vessels of varying sizes, leading to suboptimal visualization during procedures like pullback.
Innovation Solution
An adaptive vessel visualization system that automatically adjusts the scale or magnification of intraluminal images based on the measured or computed size of the vessel, ensuring that vessels of different sizes are displayed at a consistent scale on the imaging system's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed scale based on transducer depth of view is used for displaying intraluminal images, then the display system is simple and consistent, but vessels of different sizes occupy different display areas making anatomical details difficult to compare
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed display scale to a dynamic adaptive scale that automatically adjusts based on the measured lumen diameter. The processor continuously monitors lumen size and modifies the display magnification accordingly, ensuring that lumens of varying sizes consistently occupy the same display area while preserving anatomical detail visibility.
Solution Approach 2:
The patent changes the display parameter (magnification factor) based on the measured lumen diameter parameter. When the lumen diameter is detected to be smaller than a reference value, the system increases the magnification factor; when larger, it decreases the magnification factor. This parameter adaptation resolves the contradiction by maintaining consistent visual representation across different vessel sizes.
2Measurement precision
If the display magnification is increased to show small lumens clearly, then small vessel details are visible, but large vessels occupy excessive display area and lose contextual context
Solution Approach 1:
The system dynamically adjusts the display magnification parameter based on the measured lumen diameter. For small lumens, the magnification factor is increased to enhance visibility of anatomical details. For large lumens, the magnification factor is decreased to prevent excessive display area occupation and maintain contextual context. This adaptive parameter adjustment resolves the contradiction between detailed visualization and display area management.
3Loss of information
If manual adjustment of display scale is allowed for each vessel size, then optimal visualization can be achieved, but the system complexity and operator workload increase
Solution Approach 1:
The system implements self-service by automatically measuring the lumen diameter and adjusting the display magnification without requiring manual operator intervention. The processor continuously monitors the lumen size and autonomously modifies the display scale to optimize anatomical detail preservation. This automation eliminates the need for manual scale adjustments while maintaining optimal visualization, thereby reducing operator workload and system operational complexity.
Solution Approach 2:
The system employs feedback by continuously measuring the lumen diameter and using this information to automatically adjust the display magnification. The measured lumen size feeds back to the processor, which then modifies the display parameters accordingly. This closed-loop feedback mechanism ensures optimal anatomical detail preservation without requiring manual intervention, resolving the contradiction between information preservation and system complexity.

AI summary
Systems, methods, and devices are provided for automatically adjusting the scale or magnification of an intraluminal image on a display of an intraluminal imaging system based on a measured or computed size of the vessel. For example, a system may include a processor configured to receive, from an intraluminal imaging catheter or guidewire, a first intraluminal image of a body lumen, and compute a dimension of an anatomical feature of the body lumen based on the first intraluminal image. The processor computes a scaling factor for the first intraluminal image based on the dimension of the body lumen, scales the first intraluminal image by the scaling factor, and outputs the scaled first intraluminal image to a display in communication with the processor circuit.
