From previous examples posted to this list,
we can read DICOM tags in a macro like this:
open("
http://imagej.nih.gov/ij/images/ct.dcm.zip");
studyDescription = getInfo("0008,1030");
print("Study Description: "+ studyDescription);
This works fine.
If we select Show Info, the corresponding line is listed like this:
0008,1030 Study Description: TEMP BONE/ST NECK W
My question is:
Is there any easy way to get returned the DICOM tag name (in the above example "Study Description")
as a string if I only know the DICOM tag number?
What I want to do is something similar to this:
DicomTag = "0008,1030";
tagValue = getDicomTagValue(DicomTag);
tagName = getDicomTagName(DicomTag);
print("DICOM Tag Name: "+ tagName);
print("DICOM Tag Value: "+ tagValue);
Another question, for those who work with medical data:
If I have a DICOM three node of various scans done at the same MRI investigation,
do any of the DICOM tags describe where the scans are located in the patient?
That is, some kind of patient coordinate system that is the same for all scan?
(assuming that the patient was not moved, of course)
What I want to do is to select a certain point of interest in the patient,
and create X Y Z orthoviews of the same location in all scans.
Since I have no expertise in radiology, locating the same structure visually is not so
easy as the scans are done with different contrast methods and aligned at different angles.
If there is some kind of patient coordinate system in the DICOM tags,
I could calculate the corresponding pixel in each stack and do a reslice along each axis through that point.
