Hierarchical Brain Atlas Creation for Atrophy Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for image diagnosis of dementia, such as VSRAD, struggle with individual differences and lack quantifiability, making it difficult for doctors to observe brain atrophy in the limbic system and other areas beyond minor categories, and face challenges in uniformly defining brain sections.
Innovation Solution
A brain atlas creation apparatus that acquires brain images, classifies them into major, medium, and minor categories, and allows for category switching and visualization, enabling the display of brain sections in desired categories and facilitating intuitive analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If brain sections are extracted in the minimum unit (minor category) only, then measurement precision is improved, but adaptability deteriorates because doctors cannot observe brain atrophy in medium and major categories or functional categories
Solution Approach 1:
The patent segments the brain analysis system into multiple hierarchical categories (major category, medium category, minor category) allowing doctors to select and observe brain atrophy at different levels of granularity. This segmentation enables both precise minor category analysis and comprehensive major category observation, resolving the contradiction between measurement precision and adaptability.
2Manufacturing precision
If a fixed definition of brain sections is used, then manufacturing precision is improved, but adaptability deteriorates because definitions vary depending on literature and individual doctor requirements
Solution Approach 1:
The patent implements a dynamic brain section definition system where the category structure can be flexibly adjusted according to different literature standards and doctor requirements. The system allows dynamic switching between major, medium, and minor categories, enabling consistent analysis within each category while adapting to different observational needs.
3Measurement precision
If only anatomical categories are used, then measurement precision is improved, but adaptability deteriorates because doctors also need to observe functional categories
Solution Approach 1:
The patent creates a universal brain analysis system that handles both anatomical categories (limbic system, cerebral cortex) and functional categories through a unified hierarchical structure. The major/medium/minor category framework provides a multi-functional platform that accommodates different types of brain section definitions, enabling precise anatomical measurement while supporting functional category observation.

AI summary
The brain atlas creation apparatus includes: an image acquisition unit that acquires a brain image; a section setting unit that classifies a brain area in the brain image acquired by the image acquisition unit into a plurality of layers from a major category which is a higher layer to a minor category which is a lower layer and sets a brain section for each category; and a display control unit that performs control to switch the brain image for each category classified by the section setting unit and to display the brain image on a display unit.
