PXMOD Implementation

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.

PXMOD Correlation Model Pre-Processing Result

Map Parameters

Images of the following parameters can be generated

PXMOD Correlation Model Parameter

r	Pearson correlation coefficient.
p	Significance level, at which the null hypothesis of zero Pearson correlation is disproved.
z	Fisher's z for Pearson correlation.
rr	Spearman's rank correlation.
rs	Two-sided significance that rank correlation deviates from zero.
rc	The value of the signal cross correlation vector a the index defined below.
