Hi,
I am using leadtools v.15.I would like to insert private tag in my dicom file...I have used the following code  ....
***********************************************************************
  Dim element As DicomElement
  element = DS.InsertElement(Nothing, False, 1048647, DicomVRType.LO, False, 1)
                        If Not element Is Nothing Then
                             DS.FreeElementValue(element)
                            DS.SetStringValue(element, "SystemID", DicomCharacterSetType.Default)
                        End If
*************************************************************************
The above code inserting things like shown below...
Group         Element       Tag Descripition           VR                Length                Value
0x0010       0x0047                                            LO                10                      SystemID

But I need my result like this ...
Group         Element       Tag Descripition           VR                Length                Value
0x0010       0x0047           SystemID                  LO                10                     userinput

Can u please suggest me how to handle this issue......
As per the above code TagDescripition field is empty  and its wrongly inserted in Value field....
please correct my code
thanks in advance

Sakthi,


The SetStringValue
function will update the value of the tag, so if you want the value of the tag
to be 'userinput', then 'userinput' should be passed with the SetStringValue function.


To set the Tag
Description to SystemID, use the following line (VB.NET) in the application
that will display the tag. In other words, to view the private tag, you must
insert the tag using the following line in the application that will view the tag before loading the DICOM file.


Dim tag1 As
DicomTag = DicomTagTable.Instance.Insert(1048647, &HFFFFFFFFL, "SystemID", DicomVRType.LO, 1, 1, 1)

Thanks for replying,
I have added the code which u have sent ...but it show the same  result as mentioned before...
please go through my code...Is anything went wrong in below shown code..Please correct me....

Dim tag1 As DicomTag = DicomTagTable.Instance.Insert(1048645, &HFFFFFFFFL, "SystemID", DicomVRType.LO, 1, 1, 1)
 element = DS.InsertElement(Nothing, False, 1048645, DicomVRType.LO, False, 1)
 If Not element Is Nothing Then
    DS.FreeElementValue(element)
     DS.SetStringValue(element, "SystemID", DicomCharacterSetType.Default)
  End If
   DS.Save(filename, DicomDataSetSaveFlags.ExplicitVR)

Tag descripition is still empty....
Group         Element       Tag Descripition           VR                Length                Value
0x0010       0x0047                                            LO                10                   SystemID

sakthi,


As I told
you earlier, the SetStringValue function will update the value of the tag, so
if you want the value of the tag to be 'userinput', then 'userinput' should be passed with the SetStringValue function.


Did you try to use


Dim tag1 As
DicomTag = DicomTagTable.Instance.Insert(1048645, &HFFFFFFFFL, "SystemID",


before loading the DICOM file?

Sakthi,
Can you please create a small sample project (not your full application) that only shows the problem and does the following:
1- Load DICOM file.
2- Display DICOM file and tags.
3- Insert DICOM tags that you want (SystemID).
And I will modify this project for you.
Please include your project in a ZIP or RAR file and don't use the 'Preview' feature.

Sakhti,
You can use the following code and insert it in the menuItemOpen_Click event in our VB.NET DicomDemo in the following directory: [LEADTOOLS 15]\Examples\DotNet\VB\DicomDemo.
I have attached two images; DisplayedTag.jpg shows the Tag description of 'SystemID' and Tag value of 'UserInput'.
Code.jpg shows the code inserted and the place I inserted it in.

The Code:
'---------------------------
Dim tag1 As DicomTag = DicomTagTable.Instance.Insert(1048645, &HFFFFFFFFL, "SystemID", DicomVRType.LO, 1, 1, 1)
Dim dicomFileName As String = "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\IMAGE1.dic"
ds.Load(dicomFileName, DicomDataSetLoadFlags.None)
Dim element As DicomElement
element = ds.InsertElement(Nothing, False, 1048645, DicomVRType.LO, False, 1)
If Not element Is Nothing Then
ds.FreeElementValue(element)
ds.SetStringValue(element, "UserInput", DicomCharacterSetType.Default)
End If
ds.Save("E:\testfiles\DIC\test2.dic", DicomDataSetSaveFlags.None)

Sakthi,
If you want to retrieve the Tag value ('UserInput' in your example), you can use the following code:
'---------------
Dim element As DicomElement
Dim str As String
ds.Load(filename, DicomDataSetLoadFlags.None)
element = ds.FindFirstElement(Nothing, 1048645, False)
str = ds.GetStringValue(element, 0)
'---------------

Sakthi,
What are the exact tag numbers that did not insert? Are they all even or are any of them odd (e.g. ends with 1, 3, 5, ...)?

Sakthi,
You are inserting tags with even numbers, such as 1048646, 48 an 50. Only insert ODD tags that end with (1, 3, 5, 7, 9).
Please read the topic 'Private Data Elements' in the .NET help file.
