Acquisition and Data Requirements

Image Data

Any dynamic volume data.

Model Preprocessing

The reference signal will be used for the pixel-wise correlation must be defined as a file or as a VOI.

PXMOD Correlation Model Pre-Processing

Index

The index of the element in the cross correlation vector to return as rc.

It is shown in the Results panel of model preprocessing.
