Elastix

Elastix is an open-source medical image registration toolkit designed for aligning and transforming medical images using rigid and non-rigid registration techniques. Built on top of the Insight Segmentation and Registration Toolkit (ITK), Elastix is widely used in medical imaging, research, and computer vision applications for accurate image analysis across different modalities such as CT, MRI, and PET scans.

Features of Elastix :

• Open-source medical image registration framework based on ITK.
• Supports rigid, affine, and deformable (non-rigid) transformations.
• Highly configurable using parameter files without code modification.
• Provides multi-resolution optimization for accurate alignment.
• Includes Transformix for applying transformations to images and points.

Elastix Usage:

$ sudo su
$ apt update
$ cd /tmp
$ elastix --version
