Look up what a Dicom tag represents

Version 15 and .Net

At present I am retrieving DICOM elements as so:

dataSet.FindFirstElement(null, DicomTagType.PatientName, true);

This works fine if i know the type of DicomTag im working with but.....

If I have a user inputs a tag they want to see the value of i.e is there a way to find out the DicomTagType of this value (in this case patient name).

OR is there a way to get the dicom element by giving the tag itself without knowing the tagType:

dataSet.FindFirstElement(null, , true);

- i know that would never work but its just as an illustration so that you'll know what Im asking

Thanks

OK THE ABOVE DIDNT LIKE ME PUTTING TAG VALUES IN:

Version 15 and .Net

This works fine if i know the type of DicomTag im working with but.....

If a user inputs a tag that they want to see the value of i.e 1010,1010 is there a way to find out the DicomTagType of this value (in this case patient name).

dataSet.FindFirstElement(null, 1010,1010, true);

//If you have a string that contains the group number
string strGroup = "0010";
//and another string that contains the element number
string strElmnt = "0010";
//you can combine them into one number and convert it to a 32-bit value like this:
Int32 nTag = Int32.Parse(strGroup + strElmnt, System.Globalization.NumberStyles.HexNumber);
// you can then convert the value to DicomTagType by casting like this:
Leadtools.Dicom.DicomTagType tagValue = (Leadtools.Dicom.DicomTagType)nTag;
//the following line should display "PatientName"
MessageBox.Show(tagValue.ToString());

If this is not what you want, please explain it in more details.

Thats brilliant thanks!!

A related question though, Is there a way to get a list of all supported DICOM Tags from leadtools through code. For example in the case I wantzed to populate a ComboBox with all dicom tags?

Thanks for the help

You can use the following functions from the DicomTagTable Class that will help you get and navigate the Data Element Tag Table:
GetFirst
GetLast
GetNext
GetPrevious
GetCount

Please see the help topic "DicomTagTable Class Members" for information about these functions. Also, you can find source code in our C# DICOM demo in the "ElementTagDlg_Load" function call that get the tags and put them in a ListView control.
