Detailed Description

Crop a volume to the specified region of interest.

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

1. 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.
2. 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 interes (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
