kernelkit.fdk

kernelkit.fdk(projections: Any, projection_geometry: Any, volume_geometry: VolumeGeometry, filter: Any = 'ramlak', **bp_kwargs)

Feldkamp-Davis-Kress algorithm for conebeam geometry.

Parameters:

projectionsarray-like

The projections to reconstruct from.

projection_geometrylist[ProjectionGeometry]

The projection geometries.

volume_geometryVolumeGeometry

The volume geometry.

filterAny, optional

The filter to apply to the projections before backprojection. Default is ‘ramlak’. See kernelkit.processing.filter for more information.

bp_kwargsdict, optional

Keyword arguments to pass to the bp function. See kernelkit.algo.bp for more information.

See also

kernelkit.algo.bp

Backprojection function.

Notes

The FDK algorithm is a special case of the bp function, with a VoxelDrivenConeBP kernel and a filter. See the article by Feldkamp et al. [1] for more information.
