Registration

Align 2-D and 3-D medical images using rigid and deformable registration

Use medical image registration functions and the Medical Registration Estimator app to align related pairs of images or volumes. To get started with the app, see Get Started with Medical Registration Estimator. For more information on the types of registration functionality in the toolbox, see Medical Image Registration.
