Medical image registration with SimpleITK

As discussed, the objective of registration is to estimate the transformation that associates the points in given input images. The transformation estimated via registration is said to map points from the fixed to the moving image coordinate system. SimpleITK provides a configurable multi-resolution registration framework, implemented in the ImageRegistrationMethod class. To create a specific registration instance using ImageRegistrationMethod, you need to select several components that together define the registration instance:

• Transformation
• Similarity metric
• Optimizer
• Interpolator

The following diagram shows the components of the registration framework in SimpleITK:
