Behavior#

The goal of this widget is to allow the user to define a normalization to be applied to sinograms. The normalization options are:

  • None: No extra normalization will be applied to the sinogram.

  • chebyshev: Chebyshev normalization will be applied to the sinograms.

  • division: A value or an array of values will divide the sinogram (during the Nabu preprocessing step).

  • subtraction: A value or an array of values will subtract from the sinogram (during the Nabu preprocessing step).

For division and subtraction, the user can provide:

  • A scalar value, which will remain constant.

  • A region of interest (ROI) to compute one scalar value per projection to be applied to the sinogram.

  • A URL to be provided directly to Nabu. In this case, the dataset can be provided locally or globally. - If provided locally, the path will be updated for each scan. - If provided globally, it will remain constant.
