Modifying or Adding a dicom tag

Dealing with a few DICOM and DICONDE images(.dcm) and wanted to add new tags to those images.

I am using DICOM Browser to check the meta information of the image. It allows me to edit the value but I want to modify the tag name also, for example, from Patient ID to Component ID.

Just wondering if i have to change that in the dictionary. Where can i find the dictionary and modify it to add/edit tags.

Regards
Vish

As CharlesB points out, the tag keys carry no semantic value descriptions - they're just numbers as specified in the Dicom standard. Manufacturers often add custom fields, but since the meaning of these values is not explicit in the dicoms, they have to tell you what the values mean. It's usually frustrating to deal with this custom data. Please don't do this unless you have a good reason.

The dictionary that link tags' (group, element) pairs to Tag name is not saved in the DICOM data, but defined privately by the editor/viewer, with respect to the DICOM standard.

There's no way to change it.
