Image data from PACS

[bdelman]

While I have been able to use findscu to query PACS to get DICOM tags on the image level, most of the fields I request do not return values. Should I be able to retrieve ANY tag from an image on a PACS server, or are some tags (e.g., image slice thickness) simply not retrievable with findscu?

Hi,

only very few attributes are required for the PACS to support. Most of them are optional. A list can be found in the standard, part 4 (look after section about Query/Retrieve).

Best regards,
Michael

Thank you. This was helpful.

Out of curiosity, do you know if PACS administrators typically have the ability to change the image tags returned? Right now I get only:

In case this would be helpful, this is the syntax for tag query I am using with findscu:

Hi,

do you know if PACS administrators typically have the ability to change the image tags returned?

Usually some tags can be configured but that totally depends on the very product. However, you often (and normall must) find information about the attributes supported by the PACS in the PACS' conformance statement. As a customer you should have that document; if not, it is usually accessible online from the vendor's homepage.

Best regards,
Michael

Thank you. That confirms what I had thought.

From where can i found below for standards ?

A list can be found in the standard, part 4 (look after section about Query/Retrieve).

You can download the DICOM standard from the NEMA.
