🏷️ Tech Stack Badges

---

🚀 Overview

HealthAI is an end-to-end medical imaging project that detects multiple chest diseases from X-ray images using a deep learning model trained on the CheXpert dataset. It features:

• 📸 Multi-Disease Chest X-Ray Classification (supports 5+ pathologies)
• 🧠 CNN/Transfer Learning Model (EfficientNetB0)
• ⚙️ FastAPI Backend for AI Inference
• 🧩 Streamlit Dashboard for Real-time Diagnosis
• ☁️ Cloud Deployment on Render
• 🔒 Clean architecture, modular API, scalable structure

This project demonstrates real-world deep learning workflow: data pipeline → model training → evaluation → API → UI → deployment.

🧠 Features

✔ 1. Multi-Label Disease Detection

Predicts probability for diseases such as:

• Atelectasis
• Cardiomegaly
• Consolidation
• Edema
• Pleural Effusion

Example output:

{
  "Atelectasis": 0.14,
  "Cardiomegaly": 0.02,
  "Consolidation": 0.51,
  "Edema": 0.09,
  "Pleural Effusion": 0.78
}

---

✔ 2. FastAPI Backend

Endpoints:

POST /predict-xray

• Accepts an uploaded X-ray image
• Returns normalized probabilities for all diseases

GET /health

Health check endpoint

---

✔ 3. Streamlit Dashboard

• Upload X-ray image
• Call backend API
• Display disease probabilities in clean UI
• Visual + interactive

---

✔ 4. Cloud Deployment

Backend deployed on Render, accessible publicly.
