Sarepy’s documentation¶
Welcome to Sarepy’s documentation about removing ring artifacts in tomography. This documentation is not only to explain functions used in the Sarepy package but also to cover the following topics:
Causes of ring artifacts.
Classification of ring artifacts.
How ring removal methods work; pros and cons of each method; how to use them efficiently; and how to improve them.
Applications of the methods.
