## 🚀 How to Continue Development

### 1. **Start the Backend**
```bash
# Install dependencies
pip install -r requirements.txt

# Start the server
python start_gui.py

# Verify with test
python test_gui.py
```

### 2. **Setup Frontend**
```bash
cd gui/frontend
npx create-react-app . --template typescript
npm install @mui/material @emotion/react @emotion/styled
npm install axios react-router-dom
npm install @types/node @types/react @types/react-dom
```

### 3. **Development Workflow**
- Backend API available at: http://localhost:8000
- API documentation at: http://localhost:8000/docs
- Frontend will run at: http://localhost:3000
- Real-time API testing with interactive docs

## 🏗️ Architecture Summary

### Backend (✅ Complete)
```
gui/backend/
├── main.py          # FastAPI app with CORS and static serving
├── models.py        # Database models with in-memory storage
└── api/
    └── routes.py    # Clinical workflow endpoints
```

### API Endpoints (✅ Functional)
- **Health**: `GET /api/health` - System status
- **Upload**: `POST /api/upload` - DICOM file upload
- **Studies**: `GET /api/studies` - List patient studies
- **Prediction**: `POST /api/predict` - Run AI analysis
- **Reports**: `POST /api/reports` - Generate clinical reports
- **Models**: `GET /api/models` - Available AI models
- **Patients**: `GET /api/patients` - Patient management

### Frontend (📋 Planned)
```
