Examples
========

This section demonstrates practical applications of the `diffct` library for various computed tomography (CT) reconstruction tasks. Each example provides comprehensive mathematical background, implementation details, and complete working code.

The examples are organized into two main categories:

**Analytical Reconstruction Methods**
- Filtered backprojection (FBP) algorithms for direct reconstruction
- Standard analytical approaches used in clinical and research settings

**Iterative Reconstruction Methods**  
- Gradient-based optimization approaches using differentiable operators
- Advanced reconstruction techniques with regularization capabilities
