How to save measurements into a Dicom file

#1 Post by richardander » Tue, 2020-12-29, 21:33

Hello,

My program does some measurements on a dicom image. I would like to store the measurements ( text format in xml structure, less than 200KB in size) into the same image.

Questions are:

1. Is there any public DICOM header tag I can use?

2. If I have to use private ones, is there any recommendation of the range of tags?

Thank you!

I cannot see any relation to the DCMTK but...

The measurements should not be stored in the DICOM image but as a separate SOP instance. Depending on the type of your measurements, you should use the specific measurement IOD (e.g. for ophthalmology) or one of the Structured Reporting IODs with a suitable template (e.g. for ultrasound).
Storing proprietary data in a DICOM image is (almost always) the worst solution.
