Insert DICOM Tag about dcmjs HOT 5 CLOSED

I'm afraid it's more complicated than that...

If you are looking at Tag Description on a system that doesn't know about your private tag (it isn't in the receiver's dicom data dictrionary) then it has no way of knowing the description. Private tags are ones where the group is an odd number and for yours the group is 0009, so by default nobody but you knows what the values mean. The most it can do is display the text.

Plus, adding private tags is more complex than just adding them to the dataset. You can google for the details, but here's a place to start.

Once you understand how it should be laid out, you can create the required elements with dcmjs. You have a look at the discussion here about adding standard elements to the dataset: #64

I have another Question, whenever I tried to write the tag datas inside the DICOM file using dcmjs npm. Private Tags are added correctly but I can see that the rest of the tag datas are getting modified. Not all tag datas (But some datas which doesn't hold values or some Tag datas which has numeric has its value ). The tag length and VM Value is getting changed. Even though I am not writing any code to modify the existing Tag details rather than inserting a new one.

From the below Tags you can see the tags which holds 0 is taking as empty spacae and also wherever the tag value is numeric those datas are modified to empty space and the length as 0

Original Tags
goupelement Tag Desc. VR VM len Value
(0010,1020) PatientSize DS 1 2 0
(0010,1030) PatientWeight DS 1 2 0
(0018,0022) ScanOptions CS 1 6 HELIX
(0018,0050) SliceThickness DS 1 2 2

Modified After a Write Operation:
goupelement Tag Desc. VR VM len Value
(0010,1020) PatientSize DS 0 0
(0010,1030) PatientWeight DS 0 0
(0018,0022) ScanOptions CS 1 6 HELIX
(0018,0050) SliceThickness DS 0 0

Sounds like this is related to your questions in #90. Your testing is very helpful, so we should try to get this sorted out. Can you try creating a simple example script + dataset to use for debugging?

Should be fixed by the merge of #96
