Module: Elastic Slice Alignment ()

Description:

This module is experimental. Experimental features offer a preview of features to come in future releases of . Note that no technical support will be provided for experimental features.

This module computes an elastic registration of a 2D image with a 2D reference image. The registration method, which models the deformation of an elastic body, is described in:

J. Modersitzki (2004): Numerical methods for image registration. Oxford University Press, New York.

The output of the module is a single registered image. Note: Also some debug information is produced in the Project View. This should be removed before this module is released as a product.

Connections:

Data [required]
The input data must be a 3D, 8-bit gray-value image consisting of 2 images stacked in the z-direction. The first image (z=0) is the reference image, the second (z=1) is the image to be transformed.

Ports:

Material parameters

Material parameters (Lamé constants). This registration method models the image as a sheet of material that is subject to forces, defined by the image intensities, using the Navier-Lamé equations. The material properties determine how the sheet reacts to these forces. Typically, is set to 0. In this case, the sections become more rigid on increasing value of .

Parameter settings

The values of the Material parameters can either be set fixed or estimated automatically. The automatic estimation is described in Modersitzki(2004).

Iterations

Number of iterations to be performed.

Maximal displacement

Maximal displacement of a voxel per iteration.
