Purpose

The module SetWorldMatrix copies the voxel-to-world-matrix from a reference image or composes anew matrix using elementary transforms.

Details

The world matrix of the output image is calculated by matrix multiplication using the original matrix, the reference matrix and the elementary transform according to the selected status of the fields Source Image Matrix, Reference Image Matrix, and Elementary Transforms.

Finally, the result is inverted on request:

RES = inv_or_id( ELM * REF * SRC )

where ELM, REF, and SRC are matrix, inverted matrix, or identity according to the settings of the usage-fields. If Set C-dimension info, Set T-dimension info, or Set U-dimension info are selected, information of the respective data dimension are forwarded from the reference image.

Input Fields

The module has two input images. Data from input0 are transfered to the output, input1 is used in calculating the new world matrix if requested.

input0

name: input0, type: Image

Source image

input1

name: input1, type: Image

Reference image

Output Fields

output0

name: output0, type: Image

The module has one output. Data are copied from input0, the world matrix is calculated according to selected parameters.
