Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clinical methods for diagnosing neurodegenerative diseases like Alzheimer's are limited by low spatial resolution in MRI scans, allowing for early detection only in late stages of tissue damage, which hinders pre-symptomatic intervention and effective drug candidate evaluation.
Innovation Solution
An image analysis platform that processes MRI data using microstructural models to assess voxel-level congruence, enabling early diagnosis of neurodegenerative disorders by determining the disorder state of brain tissue with high accuracy through computer-processed MRI and simulated parameter comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI scans are used for brain imaging, then non-invasive tissue visualization is achieved, but spatial resolution remains low (mm dimensions) preventing detection of sub-micron structural changes
Solution Approach 1:
The patent introduces a computational intermediary (image processing algorithm) that bridges the gap between low-resolution MRI data and high-resolution tissue microstructure information. The algorithm processes MRI signal intensities to infer sub-voxel structural characteristics, effectively using computation as a mediator to overcome the physical resolution limits of the imaging hardware.
Solution Approach 2:
The patent replaces the need for high-resolution physical imaging hardware with a computational approach. Instead of relying on improved MRI scanner hardware to achieve sub-micron resolution, the invention uses software-based image processing to extract fine structural details from standard-resolution scans, substituting mechanical/improving hardware complexity with computational methods.
2Measurement precision
If current MRI diagnostic methods are used, then late-stage neurodegenerative disease detection is possible, but early-stage and pre-symptomatic diagnosis cannot be achieved
Solution Approach 1:
The patent enables preliminary detection of neurodegenerative changes before they become clinically apparent. By analyzing subtle alterations in tissue microstructure that precede symptomatic manifestation, the system performs preliminary action in the diagnostic process, allowing early intervention before full disease development.
Solution Approach 2:
The patent transforms the diagnostic parameters from macroscopic anatomical measurements to microscopic tissue microstructure characteristics. By changing the measurement parameters to include cellular-level structural features, the system can detect early pathological changes that are invisible to conventional MRI analysis methods.
3Measurement precision
If conventional diagnostic approaches are used, then differential diagnosis can be performed, but accurate early-stage diagnosis with high precision is not achievable
Solution Approach 1:
The patent introduces computational algorithms as intermediaries that process and enhance the diagnostic information extracted from MRI scans. These computational mediators bridge the gap between standard imaging capabilities and high-precision diagnostic requirements, enabling accurate early-stage detection without proportionally increasing hardware complexity.
