Brain Tomographic Image Subtraction and Projection for Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic systems face challenges in comprehensively examining and presenting abnormalities across multiple anatomical regions of the brain, making it difficult to provide effective diagnosis support.
Innovation Solution
A diagnostic imaging support system that acquires and processes tomographic image data, generates subtracted and projection image data, and displays these images in a way that allows for rotation and coordinate-based visualization, enabling the display of specific cross-sectional images and facilitating the identification of abnormalities across multiple anatomical regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple anatomical regions are comprehensively examined individually, then measurement precision of each region is improved, but device complexity and difficulty of presenting abnormalities increases
Solution Approach 1:
The system segments the brain into multiple anatomical regions (parahippocampal gyrus, hippocampus, amygdala, etc.) and processes each region separately through automated segmentation algorithms, achieving precise measurement of each region while maintaining system efficiency
Solution Approach 2:
The system introduces an intermediary integration module that consolidates measurement results from multiple anatomical regions into a unified presentation format, reducing the complexity of displaying abnormalities across multiple regions simultaneously
2Measurement precision
If multiple anatomical regions are comprehensively examined individually, then measurement precision of each region is improved, but ease of operation decreases
Solution Approach 1:
The system merges the examination of multiple anatomical regions into a single integrated workflow, automatically processing and presenting abnormalities across all regions (parahippocampal gyrus, hippocampus, amygdala, etc.) without requiring separate manual examinations, thereby maintaining measurement precision while improving ease of operation
3Measurement precision
If detailed information of each anatomical region is obtained, then measurement precision is improved, but loss of information increases due to difficulty in comprehensive presentation
Solution Approach 1:
The system transitions from two-dimensional individual region presentations to a three-dimensional integrated visualization that displays multiple anatomical regions (parahippocampal gyrus, hippocampus, amygdala, etc.) and their abnormalities in spatial context, preserving detailed measurement information while enabling comprehensive presentation

AI summary
A diagnosis support system that causes at least one memory and at least one processor to acquire first tomographic image data and second tomographic image data containing a plurality of cross-sectional images, acquire subtracted image data generated by performing subtraction between the first tomographic image data and the second tomographic image data, acquire projection image data generated by performing projection processing in a projection direction parallel with a cross-sectional surface of the plurality of cross-sectional images on the subtracted image data, wherein the projection image data can be displayed in rotation with a stacking direction of the plurality of cross-sectional images as a rotation axis, and the projection direction is substantially perpendicular to the stacking direction, and display a projection image based on the projection image data.
