3.2.2 DWI-B0 Registration (1)

For this page and subsequent pages describing the registration settings file options the first bulleted item indicates the name of the settings tag, the next indented bulleted items indicate the possible options. The option in blue is the default setting.

  • <effect></effect>
    • rigid
    • motion_distortion Default Setting

The first operation that the program performs is the motion correction and eddy current distortion correction. This tag in the registration settings file determines which type of correction is performed.

If "rigid" is chosen, only rigid body transformations are considered therefore only motion artifacts are corrected.

If "motion_distortion" is chosen, both rigid body transformations and eddy current related distortion transformations are considered and corrected.

In most cases, the "motion_distortion" option is the better one and is set as the default option.
