DicomVR Class

Summary

The DicomVR class contains information about supported value representations.

Syntax

Objective-C

C++/CLI

Java

public class DicomVR

@interface LTDicomVR : NSObject

public class DicomVr

public ref class DicomVR

Remarks

Internally LEADTOOLS maintains a table or list of available value representations. These value representations can include default value representations available in DICOM, as well as user defined value representations. You can access any of this information, add to the table, or delete items from the table using the methods of the DicomVRTable class.

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestVRTable() 
{ 
 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
 
   //We don't need to call this since the DicomEngine.Startup already does that for us 
   //These calls are for demonstration purposes only 
   DicomVRTable.Instance.Reset(); 
   DicomVRTable.Instance.Default(); 
 
   //We can also call FindByIndex if we know the index of this VR 
   DicomVR vr = DicomVRTable.Instance.Find(DicomVRType.AE); 
   DicomVRTable.Instance.Delete(vr); 
 
   DicomVR vr1 = DicomVRTable.Instance.Insert(DicomVRType.AE, "My AE VR", 16, DicomVRRestriction.StringFixed, 1); 
   Debug.Assert(DicomVRTable.Instance.Exists(vr1) == true); 
   DicomVRTable.Instance.SetName(vr1, "My New AE VR"); 
 
   int count = 0; 
   //If we want to loop through all the VRs in the table we can do this: 
   vr = DicomVRTable.Instance.GetFirst(); 
   while (vr != null) 
   { 
      // We can also access the rest of the properties of DicomVR in here, 
      // such as DicomVRType.Code, DicomVRType.Length, DicomVRType.Name, 
      // DicomVRType.Restriction and DicomVRType.UnitSize 
      if (vr.Code == DicomVRType.AE) 
      { 
         Console.WriteLine(vr.Name); 
      } 
      count++; 
      vr = DicomVRTable.Instance.GetNext(vr); 
   } 
   //We can use GetLast and GetPrevious to achieve the same thing 
 
   Debug.Assert(count == DicomVRTable.Instance.GetCount()); 
 
   DicomEngine.Shutdown(); 
}
