MEDISON-AI: A Multi-Module Integrated Intelligent Medical Diagnosis Assistance System

MEDISON-AI is an intelligent medical diagnosis assistance system that integrates five core modules: disease prediction, medical document OCR, skin disease detection, AI chatbot, and health record management. The system is implemented using technologies such as Random Forest, CNN, and TF-IDF, covering diverse medical scenarios with a modular architecture. Positioned as an auxiliary tool for professional medical diagnosis, it aims to provide preliminary assessment services for areas with insufficient medical resources.

As a comprehensive intelligent medical diagnosis assistance system, MEDISON-AI adopts a modular architecture design, decomposing complex diagnosis processes into specialized subsystems. This multi-module integration concept reflects a trend in the medical AI field: a single model can hardly handle the diversity of scenarios, while combining multiple professional models can cover broader needs while maintaining maintainability.

Technical Implementation of Core Modules

1. Disease Prediction Module: Based on Random Forest classifier, with 92.3% accuracy on the training set and 89.7% on the test set, effectively reducing overfitting risks;
2. Medical Document OCR Module: Uses Tesseract engine, supports over 100 languages, breaking down the barrier between paper records and digital systems;
3. Skin Disease Detection Module: Implemented based on CNN, with 85.4% accuracy, automatically learning hierarchical features of images;
4. AI Chatbot Module: Adopts TF-IDF and cosine similarity matching, featuring strong determinism and high interpretability;
5. Health Record Management Module: Based on SQLite database, enabling lightweight local storage and query.

Technology selection reflects a pragmatic implementation approach:

• Random Forest: Suitable for structured medical data, performs well on small and medium datasets, has low training cost, and high interpretability;
• Tesseract: Open-source solution lowers deployment thresholds, suitable for individual developers and small institutions;
• Retrieval-based Q&A: Avoids hallucination risks of generative models and provides answer traceability;
• SQLite: Lightweight and zero-configuration, adapting to local management needs of personal health records.

Application scenarios focus on areas with insufficient medical resources:

• Preliminary screening: Identifying cases requiring urgent referral;
• Health record digitization: Converting paper medical records into searchable electronic records;
• Patient education: Answering common health questions via chatbot;
• Skin disease self-check: Providing preliminary judgments for users who cannot seek medical attention in time. Note: This system is only an auxiliary tool; the final diagnosis must be made by professional medical personnel.

Current limitations and improvement directions:

1. Limited dataset size; expanding data can improve model performance;
2. Lack of model update and version management mechanisms, needing to adapt to the evolution of medical knowledge;
3. Mainly supports English scenarios, needing to expand multilingual capabilities;
4. Requires strict clinical trial validation before actual deployment.

MEDISON-AI represents a pragmatic approach to medical AI development: achieving function coverage through modular combination, reducing development and maintenance costs, and enhancing scalability. For medical AI developers, the project provides a reference for clear code structure and reasonable technology selection. Note: Deployment of medical AI must strictly comply with regulations and undergo sufficient clinical validation.
