Coregistration

The Coregistration component uses SPM12 to coregister two volumes using a rigid body transformation (i.e., it does neither zoom nor shear). This type of Coregistration should be used if all the imaging is from the same patient. It is not advised to use for atlas coregistration. If you are having issues with the standard version of spm12, consider using the developer version from GitHub. This resolves some issues with macOS Sonoma and with MATLAB 2024a and above.

Inputs and Outputs

• Inputs: Reference Volume, Volume you want to have coregistered

• Outputs: Coregistered Volume, Transformation Matrix

Settings

Properties can be set via the Pipeline Workflow File

Reference Volume - This volume will not be changed Default: MRI

CoregistrationIdentifier

Image that will be coregistered Default: CT

TIdentifier

Identifier of the Transformation Matrix which results in aligning the images (This matrix is already applied to the output volume).

Default: T
