Module Description

Orients an output volume. Rearranges the slices in a volume according to the selected orientation. The slices are not interpolated. They are just reordered and/or permuted. The resulting volume will cover the original volume. NOTE: since Slicer takes into account the orientation of a volume, the re-oriented volume will not show any difference from the original volume, To see the difference, save the volume and display it with a system that either ignores the orientation of the image (e.g. Paraview) or displays individual images.

Use Cases

  • This module is useful for transforming volume from its original orientation to a given orientation. Note, that the module does not align the voxel space axes with the physical space axes. If your input image is not axis-aligned, the output will preserve the direction cosines of the input image. It does not change the spatial position and orientation of the volume in the physical space.

When combined with "Create a Dicom Series" module, one can synthesize a sagittal acquisition from an axially acquired volume.

  • A command line example of the module is
   --orientation Axial 


./OrientImage  [--processinformationaddress <std::string>] [--xml]
               [--echo] [-o <Axial|Coronal|Sagittal|RIP|LIP|RSP|LSP|RIA
               |ASL>] [--] [--version] [-h] <std::string> <std::string>


--processinformationaddress <std::string>
  Address of a structure to store process information (progress, abort,
  etc.). (default: 0)

  Produce xml description of command line arguments (default: 0)

  Echo the command line arguments (default: 0)

   |PSL|AIL|ASL>,  --orientation <Axial|Coronal|Sagittal|RIP|LIP|RSP|LSP
  Orientation choices (default: LPS)

--,  --ignore_rest
  Ignores the rest of the labeled arguments following this flag.

  Displays version information and exits.

-h,  --help
