Solution Overview
Problem
Current methods for measuring aneurysm size, such as coil embolization, rely on approximate polyhedral shapes, which lack precision and do not accurately represent the complex shape of aneurysms.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If polyhedral shapes are used to approximate aneurysm size, then the measurement process is simple, but the measurement precision is poor
Solution Approach 1:
The patent applies segmentation by dividing the complex aneurysm structure into a mesh of discrete elements (vertices, edges, and faces). This allows the aneurysm to be represented as a collection of simpler geometric components that can be processed computationally, enabling precise measurement while managing complexity through systematic decomposition.
Solution Approach 2:
The patent creates a digital mesh copy of the aneurysm structure from medical images. This virtual replica preserves the aneurysm's complex geometry without requiring physical manipulation of the actual aneurysm, allowing for precise measurements and analyses while simplifying the measurement process through computational methods.
2Measurement precision
If traditional image analysis methods are used, then the process is fast, but the measurement precision is insufficient for accurate treatment planning
Solution Approach 1:
The patent performs preliminary processing by automatically generating the vessel mesh and identifying adhered vessels before the actual measurement and analysis steps. This preparation work is done in advance using image processing algorithms, which reduces the time required for subsequent measurements and enables more precise analysis without increasing overall processing time.
Solution Approach 2:
The patent replaces manual mechanical measurement methods with automated computational algorithms. The mesh structure enables computer-based calculation of volume, surface area, and other dimensions, substituting manual analysis with automated processing that is both faster and more precise.
3Measurement precision
If adhered vessels are not separated, then the vascular structure remains intact, but the aneurysm measurement accuracy is reduced
Solution Approach 1:
The patent extracts and separates adhered vessels from the main vascular structure by identifying them as distinct elements in the mesh. This extraction allows the aneurysm region to be isolated and measured independently, improving measurement accuracy while the automated extraction process keeps the operation manageable.
Solution Approach 2:
The patent applies different processing qualities to different parts of the vascular structure. Adhered vessels are identified and handled differently from the main vessel structure, with specific algorithms applied to separate and isolate these regions. This localized differentiation enables accurate aneurysm measurement while maintaining the integrity of the overall vascular model.
