incomplete reading of metadata

Hello.

since the software upgrade of our radiography device (DX), the column of "patient name" and "patient ID" has been stopped filling out. Other field attributes are reported correctly

The metadata data on my PACS is reported correctly in the patient's name and patient ID .

External exams and old tests before the software upgrade show all fields correctly after export.

It should be a problem for the equipment manufacturer. Does anyone have any tips I can point out to the company?

Thank you

Burkard

Hi

Are there other devices? Are they still showing the patient details on exports if they have been imported after the change was noticed?

If so, that should rule out a change on the Patient ID config menu (https://docs.openrem.org/en/0.10.0-docs/patientid.html#configure-what-is-stored)

The next thing to do would be to have a look at the DICOM headers to see if there is a difference. If you have a QA image from after the upgrade, then you are welcome to send it to me and I can take a look at it to see where the issue might be.

Kind regards

Ed

Thanks for confirming the other modalities are still working fine, and thanks for sending through an example image.

I can confirm that I can see the same behaviour, so I'll step through the extraction process and work out what is going on - it might be a few days before I get to it though.

Kind regards

Hi Burkard

The issue is that the PatientSize value, which should be a number (ie height), has been populated with a string "MEDIUM". This isn't currently checked for, as it is not allowed according to the standard and the value representation type.

However, I have added code to check for this that will be in the next release: https://bitbucket.org/openrem/openrem/pull-requests/447/issue896checkptsize

In the meantime, I suggest you go back to the vendor and explain the issue. You could also try to make the same modification in the dx.py module in your installation.
