DicomUidOrgRoot Property


Gets or sets a numeric string representing an organization root that is used when generating a DICOM Unique Identifier (UID).

public string DicomUidOrgRoot { get; set; } 
Public Property DicomUidOrgRoot() As String 
   property String^ DicomUidOrgRoot 
      String^ get() 
      void set(String^ value) 

Property Value

An organization root that is used when generating a DICOM Unique Identifier (UID).


A DICOM UID is a character string containing a UID that is used to uniquely identify a wide variety of items.

The UID is a series of numeric components separated by the period "." character.

The method FromAnnContainerToDataSet(DicomDataSet,AnnContainer,DicomDataSet,string,string,FromAnnContainerToDataSetOptions) converts an AnnContainer to a DicomDataSet. During the conversion, a new SeriesInstanceUID and SOPInstanceUID are optionally generated by passing string.Empty for these arguments.

The generated UIDS will always start with the string specified by DicomUidOrgRoot.

The default value for DicomUidOrgRoot is "1.2.840.114257.1.1".

For the DicomUidOrgRoot:

  • 1 identifies ISO.
  • 2 identifies the ISO member body branch.
  • 840 identifies the country code of a specific ISO member body (U.S. for ANSI).
  • 114257 identifies the LEAD Technologies, Inc. organization root as registered by the ISO member body ANSI.

This example stores DICOM annotations for two different DICOM instances in the same DICOM presentation file. The DICOM annotations are then loaded separately for each DICOM instance.
When running this sample, two different DICOM instances must be passed for the same PatientID.
The following DICOM files can be used:

  1. C:\LEADTOOLS22\Examples\Medical\DotNet\PACSDatabaseConfigurationDemo\Resources\cr1.dcm
  2. C:\LEADTOOLS22\Examples\Medical\DotNet\PACSDatabaseConfigurationDemo\Resources\cr2.dcm
