Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intraluminal imaging systems require time-consuming manual calculations and interactions with nonsterile equipment to accurately assess lumen dimensions and constrictions during procedures like IVUS pullback, lacking direct association with vessel locations until post-treatment reports are generated.
Innovation Solution
A graphical longitudinal display system that automatically measures and calculates lumen dimensions, displaying them in a simplified format on a single screen, allowing real-time assessment of lumen conditions and treatment effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calculations and interactions with nonsterile equipment are used to assess lumen dimensions, then measurement precision can be achieved, but time consumption increases and productivity decreases
Solution Approach 1:
The system performs automatic measurements and calculations of lumen dimensions, area, percent constriction, and percent improvement without requiring manual intervention. The processor circuit automatically analyzes IVUS images and generates quantitative data, allowing the system to serve itself rather than requiring clinician manual measurement and calculation.
Solution Approach 2:
The patent replaces manual mechanical measurement processes with automated electronic processing. The processor circuit electronically analyzes ultrasound images, calculates dimensions and percentages, and generates reports automatically, substituting the mechanical manual measurement process with an automated computational system.
2Measurement precision
If detailed measurements and calculations are performed manually, then measurement precision is improved, but the complexity of operations increases
Solution Approach 1:
The system automatically performs complex measurements and calculations without requiring user intervention. The processor circuit autonomously analyzes images, computes dimensions, calculates percentages, and generates reports, eliminating the need for users to manually perform complex operational steps.
Solution Approach 2:
The processor circuit acts as an intermediary between the IVUS imaging system and the clinician. It automatically processes images, performs measurements and calculations, and presents results in a simplified format, mediating the complex technical operations so that clinicians only need to interpret the final results without dealing with complex manual measurement processes.
3Loss of information
If traditional IVUS display formats are used, then detailed image information is available, but the ease of rapid assessment is reduced
Solution Approach 1:
The system segments the assessment process into different visual components: a graphical longitudinal display showing quantitative measurements (diameter, area, percent constriction) and a traditional IVUS image display showing detailed anatomical information. This segmentation allows users to rapidly assess quantitative data while having detailed images available when needed.
Solution Approach 2:
The patent transforms the display format by changing from traditional detailed image-only displays to a hybrid display that includes graphical representations of quantitative parameters. The system visualizes measurements such as lumen diameter, cross-sectional area, and percent constriction as graphical elements, changing the parameter representation from raw numbers to visual formats that enable rapid assessment.
