BeforeTagAnonymization Event

Summary

Occurs before a tag is anonymized.

Syntax
C#
VB
C++
public event EventHandler<BeforeTagAnonymizationEventArgs> BeforeTagAnonymization 
Public Event BeforeTagAnonymization As EventHandler(Of BeforeTagAnonymizationEventArgs) 
public: 
event EventHandler<BeforeTagAnonymizationEventArgs^>^ BeforeTagAnonymization 
Event Data

The event handler receives an argument of type BeforeTagAnonymizationEventArgs containing data related to this event. The following BeforeTagAnonymizationEventArgs properties provide information specific to this event.

PropertyDescription
Cancel (Inherited from System.ComponentModel.CancelEventArgs)Gets or sets a value indicating whether the event should be canceled.
CurrentValue Gets the current value of the DICOM element.
Element Gets the element in the DICOM dataset that is being anonymized.
NewValue Gets or sets the new value of the DICOM element.
Remarks

This event will occur after the tag has been processed with the MacroProcessor.

Example

This example anonymizes a dataset using the DICOM Anonymization basic profile.

C#
VB
using Leadtools.Dicom.Common.Anonymization; 
using Leadtools.Dicom; 
 
public void AnonymizationSample() 
{ 
   Anonymizer anonymizer = new Anonymizer(); 
   string dicomFileNameIn = Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm"); 
 
   anonymizer.Progress += new EventHandler<ProgressEventArgs>(anonymizer_Progress); 
   anonymizer.BeforeTagAnonymization += new EventHandler<BeforeTagAnonymizationEventArgs>(anonymizer_BeforeTagAnonymization); 
   using (DicomDataSet source = new DicomDataSet()) 
   { 
      string oldPatientId = string.Empty; 
 
      source.Load(dicomFileNameIn, DicomDataSetLoadFlags.None); 
      oldPatientId = source.GetValue<string>(DicomTag.PatientID, string.Empty); 
      anonymizer.Anonymize(source); 
 
      // 
      // The values should not be equal because the anonymizer has provided another patient ID using the DICOM Anonymization basic profile. 
      // By default the following macro is provided for patient id: ${random_string} 
      // 
      Debug.Assert(oldPatientId != source.GetValue<string>(DicomTag.PatientID, string.Empty)); 
   } 
}
