Module Description

Program title BRAINSResample
Program version 3.0.0
Program documentation-url http://www.slicer.org/slicerWiki/index.php/Modules:BRAINSResample

BRAINSResample is a program whose purpose is to resample image volumes to a new resolution, optionally applying a transformation.

Usage

BRAINSResample collects together three common image processing tasks that all involve resampling an image volume: Resampling to a new resolution and spacing, applying a transformation (using an ITK transform IO mechanisms) and Warping (using a vector image deformation field).

Quick Tour of Features and Use

  • Inputs Parameters for specifying the image to warp and resulting image space
    • Image To Warp [--inputVolume]: Image To Warp
    • Reference Image [--referenceVolume]: Reference image used only to define the output space. If not specified, the warping is done in the same space as the image to warp.
  • Outputs Resulting deformed image parameters
    • Output Image [--outputVolume]: Resulting deformed image
    • Pixel Type [--pixelType]: Specifies the pixel type for the input/output images. The "binary" pixel type uses a modified algorithm whereby the image is read in as unsigned char, a signed distance map is created, signed distance map is resampled, and then a thresholded image of type unsigned char is written to disk.
  • Warping Parameters Parameters used to define home the image is warped
    • Deformation Field [--deformationVolume]: Deformation Field to be used to warp the image
    • Warp By Transform [--warpTransform]: Filename for the BRAINSFit transform used in place of the deformation field
    • Interpolation Mode [--interpolationMode]: Type of interpolation to be used when applying transform to moving volume. Options are Linear, NearestNeighbor, BSpline, or WindowedSinc
    • Default Value [--defaultValue]: Default voxel value
  • Advanced Options Add warped grid to output image to help show the deformation that occured with specified spacing. A spacing of 0 in a dimension indicates that grid lines should be rendered to fall exactly (i.e. do not allow displacements off that plane). This is useful for makeing a 2D image of grid lines from the 3D space
    • Add Grids [--gridSpacing]: Add warped grid to output image to help show the deformation that occured with specified spacing. A spacing of 0 in a dimension indicates that grid lines should be rendered to fall exactly (i.e. do not allow displacements off that plane). This is useful for makeing a 2D image of grid lines from the 3D space
