## Overview

Understanding ultrasound image and signal quality requires familiarity with several key concepts:

- **Ultrasound Metrics**: The mathematical measures used to quantify different aspects of image and signal quality
- **Multi-Backend Support**: How the library seamlessly works with different array computation libraries
- **Array API Design**: The technical approach that enables backend flexibility and performance

Each section provides both the theoretical background and practical implementation details relevant to using this library effectively.
