Detailed Description

Crop a volume to the specified region of interest.

This class implements cropping and resampling of a volume. Two main use cases:

Reduce size (both extent and resolution) of a large volume. Size reduction is useful, as it reduces memory need and makes visualization and processing faster.
Increase resolution of a specific region. Increasing resolution (decreasing voxel size) is useful for segmentation and visualization of fine details.

If interpolation is disabled then only the extent of the volume is decreased. Cropping without resampling is very fast and needs almost no extra memory.

If interpolation is enabled, then both the size and resolution of the volume can be changed.

Limitations:

Region of interest (ROI) node cannot be under non-linear transform
Cropped output volume node cannot be under non-linear transform
If interpolation is disabled: input volume node cannot be under non-linear transform and ROI node must be aligned with the input volume

Member Function Documentation

◆ Apply()

int vtkSlicerCropVolumeLogic::Apply ( vtkMRMLCropVolumeParametersNode * )

Crop input volume using the specified ROI node.

◆ CropInterpolated()

Perform interpolated cropping.

		bool	limitToInputExtent = true,
		double	fillValue = 0.0 )

static

Perform non-interpolated (voxel-based) cropping. If limitToInputExtent is set to true (default) then the extent can only be smaller than the input volume.

◆ FitROI()

static bool vtkSlicerCropVolumeLogic::FitROI ( vtkMRMLCropVolumeParametersNode * parametersNode )

static

Sets ROI to fit to input volume. Orientation of the ROI set based on FitROIMode setting.

◆ FitROIToInputVolume()

static bool vtkSlicerCropVolumeLogic::FitROIToInputVolume ( vtkMRMLCropVolumeParametersNode * parametersNode )

static

Sets ROI to fit to input volume. If ROI is under a non-linear transform then the ROI transform will be reset to RAS.
