java.lang.Object

edu.stanford.rsl.conrad.filtering.ImageFilteringTool

edu.stanford.rsl.conrad.filtering.multiprojection.MultiProjectionFilter

edu.stanford.rsl.conrad.reconstruction.ReconstructionFilter

All Implemented Interfaces:

Citeable, GUIConfigurable, SafeSerializable, ProjectionSink, java.io.Serializable, java.lang.Cloneable, java.lang.Runnable

Direct Known Subclasses:

FBPReconstructionFilter, IterativeReconstruction, IterativeReconstruction, SimpleIterativeReconstruction, SuperShortScanBackprojection

public abstract class ReconstructionFilter
extends MultiProjectionFilter

All reconstruction algorithms are based on the reconstruction filter. The reconstruction filter is the abstract class that gives the general outline of any reconstruction algorithm.

Method Detail

getGeometry

public Trajectory getGeometry()

updateVolume

public void updateVolume(int i,
                int j,
                int k,
                double increment)

updates the projection volume. Note that direct access to pixels is much faster than accessing the image data with getProcessor(), if the data type is known.

Parameters:

i - x pixel entry number

j - y pixel entry number

k - z pixel entry number

increment - the value to add.

setProjectionVolume

public void setProjectionVolume(Grid3D projectionVolume)

Used to set the projection volume. This is used in "SubVolumeBackprojector" in order to reconstruct parts of the volume in a parallel manner. Note that projection volumes should be of type FloatProcessor

Parameters:

projectionVolume - the volume

initializeProjectionVolume

public void initializeProjectionVolume()

creates an empty projection volume.

applyHounsfieldScaling

public void applyHounsfieldScaling()

applies the Hounsfield scaling as defined in the current global configuration. (Calls Configuration.getGlobalConfiguration().getHounsfieldScaling()).

prepareForSerialization

public void prepareForSerialization()

Description copied from interface: SafeSerializable

Sets all data objects in the serialized object to null which do not implement the Serializable interface. It can also be used to save space in the serialized form. Configuration parameters are preserved. Processing data is discarded.

Specified by:

prepareForSerialization in interface SafeSerializable

Overrides:

prepareForSerialization in class MultiProjectionFilter
