Solution Overview
Problem
Current medical imaging technologies require extensive human interaction and resources for setup, operation, and annotation, and existing collaborative annotation platforms are inadequate for handling medical imaging data, leading to inefficiencies and inaccuracies in dataset creation.
Innovation Solution
A web-based, zero-footprint collaborative annotation tool utilizing blockchain technology for secure, transparent, and incentivized crowdsourcing of medical imaging annotations, enabling efficient data collection and curation by trained experts, and facilitating the development of high-quality datasets for AI training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If crowdsourcing data collection methods are used for medical imaging annotation, then the quantity of annotated data increases, but the quality and accuracy of annotation deteriorates due to mislabeling by undertrained participants
Solution Approach 1:
The patent introduces an intermediary validation layer where expert annotators review and verify annotations made by crowd workers. This intermediary step filters out mislabeling while preserving the high throughput of crowdsourcing, effectively resolving the contradiction between quantity and quality of annotations.
Solution Approach 2:
The system implements feedback mechanisms where annotation quality is continuously monitored and evaluated. Annotators receive feedback on their performance, and the system uses this feedback to improve overall annotation accuracy while maintaining high productivity through iterative refinement.
2Measurement precision
If well-trained experts are involved in thorough curation process for improving database quality, then the quality of annotated data improves, but the time and resource investment increases
Solution Approach 1:
The patent applies partial expert validation where not all annotations require full expert review. Instead, a subset of annotations is randomly selected for expert verification, or only annotations that fall below certain quality thresholds are reviewed by experts, reducing overall curation time while maintaining high accuracy.
Solution Approach 2:
The system performs preliminary filtering and validation of annotations before they are added to the database. Automated quality checks and preliminary reviews are conducted upfront, reducing the need for extensive post-processing and expert intervention later, thereby reducing total curation time.
3Reliability
If blockchain technology is implemented for secure and transparent annotation tracking, then the reliability and trustworthiness of the system improves, but the device complexity and computational overhead increases
Solution Approach 1:
The patent extracts only the essential blockchain functionality needed for annotation tracking, such as hashing annotation data and storing hashes on the blockchain, rather than implementing a full blockchain system. This reduces complexity while maintaining the reliability benefits of blockchain for verification and audit purposes.
