Class Code

class OrsPythonPlugins.OrsReconstruction.OrsReconstruction.OrsReconstruction(varname=None)
classmethod OrsReconstruction_openToolbox()
UIDescriptors = [<ORSServiceClass.OrsPlugin.uidescriptor.UIDescriptor object>]
canImportFromPreview()
cleanup()

Deletes the variables managed by the plugin. It is the place to remove callbacks and other references to Python objects that would prevent them to be garbage collected. This method is called during the process of deletion of the plugin. It calls for the cleanup and deletion of the forms.

interfacemethod computePreview(projectionStack, metadata, reconstructorEngineAlgorithmInstance, sliceIndex, preProcessor, progress=None)

Reconstruct projection for slice sliceIndex following the given reconstruction engine and pre processing workflow

Parameters:
  • projectionStack (ORSModel.ors.Channel) – input projection stack to be reconstruct
  • metadata (transient Metadata) – the associated ct acquisition geometry
  • reconstructorEngineAlgorithmInstance (transient AbstractReconstructor) – the instance of the reconstruction engine
  • sliceIndex (int) – slice index
  • preProcessor (transient CTPreProcessor) – pre processing filters workflow to be applied
  • progress (ORSModel.ors.Progress) – an optional progress bar
Returns:
  • reconstructedOutputPreview (ORSModel.ors.Channel) – reconstructed preview
  • err (str) – error message if an error occur
computePreviewAndPublish()

Reconstruct the input dataset from the set instance variables. If succeed, the reconstructed dataset will be published.

Returns:
  • succeed (bool) – true if the reconstruction and publish succeed, false otherwise.
  • errorMessage (str) – detail of the error when an error occur.
createMetadataFromBeamType(beamType)
getAngularSamplingFactor()
getAvailableReconstructorEngineClassList()
getInputChannel()
getIsPreview(selectedChannel)
getIsValidParameters()
classmethod getMainFormClass()

Gets the class of the main form

Returns:output –
getMetadata()
getPreProcessingFilterInstanceList()
getPreviewCount()
getSelectedReconstructorAlgorithmInstance()
getSupportedBeamTypes()
getTiltAngleFinderInstance()
getWidgetForSelectedReconstructorAlgorithm(parent=None)
classmethod importAllLoggingClasses()

This method is called to make any class extension available for macro playing. It should:

  1. import all class extension;
  2. return a list of classes where logging is supported.
Returns:output (list of classes) – list of classes where logging is supported by the current plugin
keepAlive = False
multiple = False
interfacemethod reconstruct(projectionStack, metadata, reconstructorEngineAlgorithmInstance, preProcessor, progress=None)

Reconstruct projection following the given reconstruction engine and pre processing workflow

Parameters:
  • projectionStack (ORSModel.ors.Channel) – input projection stack to be reconstruct
  • metadata (transient Metadata) – the associated ct acquisition geometry
  • reconstructorEngineAlgorithmInstance (transient AbstractReconstructor) – the instance of the reconstruction engine
  • preProcessor (transient CTPreProcessor) – pre processing filters workflow to be applied
  • progress (ORSModel.ors.Progress) – an optional progress bar
Returns:
  • reconstructedOutputVolume (ORSModel.ors.Channel) – reconstructed volume
  • err (str) – error message if an error occur
interfacemethod reconstructAndSaveAsTiff(projectionStack, metadata, reconstructorEngineAlgorithmInstance, preProcessor, outputFileDirectory)

Reconstruct projection following the given reconstruction engine and pre processing workflow, and sava the results on disk as tiff

Parameters:
  • projectionStack (ORSModel.ors.Channel) – input projection stack to be reconstruct
  • metadata (transient Metadata) – the associated ct acquisition geometry
  • reconstructorEngineAlgorithmInstance (transient AbstractReconstructor) – the instance of the reconstruction engine
  • preProcessor (transient CTPreProcessor) – pre processing filters workflow to be applied
  • outputFileDirectory (str) – output file directory
Returns:
  • succeed (bool) – succeed or not
  • errorMessage (str) – error message
reconstructAndSaveOnDiskAsTiff(anOutputFileDirectory)
reconstructDatasetAndPublish()

Reconstruct the input dataset from the set instance variables. If succeed, the reconstructed dataset will be published.

savable = False
setAngularSamplingFactor(angularSamplingFactor)
setAsPreview(previewChannel)
setInputChannel(aChannel)
setReconstructionEngineClass(anEngineClass)
setReconstructionPluginInstanceVariableFromSelectedPreview(selectedPreview)

Update reconstruction plugin instance from a selected preview (ORS Channel)

setReconstructorAlgorithmClass(anAlgoClass)
setReconstructorEngineInstance(aClass: OrsPythonPlugins.OrsReconstruction.algorithms.baseAlgorithm.AbstractReconstructor)
startRotationFinder()
classmethod startupDefault(openMainForm=True)

Creates an instance of the plugin class and opens the main form (if required) at the default position.

Returns:output (AbstractPlugin) – plugin instance
