Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are cumbersome for assessing subtle structural changes in brain images over time, making it difficult to evaluate treatment efficacy or track brain atrophy in neurodegenerative diseases and cancerous tumors.
Innovation Solution
A system and method for overlaying and aligning brain images captured at different time points to highlight changes in size, shape, and orientation using segmentation and co-registration techniques, allowing for interactive visualization and quantitative analysis of structural differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual comparison of brain scans is performed, then diagnostic accuracy can be maintained, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent introduces an automated image processing system with overlay visualization as an intermediary between the raw brain scan data and the physician's diagnosis. The system automatically segments brain structures, aligns multiple scans, and generates visual overlays highlighting changes, thereby maintaining diagnostic accuracy while eliminating the time-consuming manual comparison process.
2Measurement precision
If detailed manual analysis of brain structure changes is performed, then measurement precision is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements self-service automation where the system automatically performs segmentation of brain structures, registration of multiple scans, calculation of structural changes, and generation of visual overlays without requiring manual intervention. This eliminates operational complexity while maintaining high measurement precision through automated algorithms.
3Productivity
If automated image processing is implemented, then productivity is improved, but measurement precision of subtle changes may deteriorate
Solution Approach 1:
The overlay visualization acts as an intermediary that preserves subtle structural changes by visually amplifying them through contour highlighting and color-coded difference maps. The system processes images automatically for speed while the overlay visualization ensures that even subtle changes remain detectable and interpretable for diagnostic purposes.
Data Source
AI summary
A system and method directed to receiving a first data set corresponding to patient data at a first time, receiving a second data set corresponding to patient data at a second time, segmenting a first region of interest in the first data set and a second region of interest in the second data set, the first and second regions corresponding to one another and aligning the first region of interest with the second region of interest to highlight a first contour indicating a change in size, shape and orientation between the first and second regions of interest.
