DICOM Modality Mapping

[awdeorio]

Is your feature request related to a problem? Please describe.
DICOM messages sometimes include a modality in the field used for identity by TapirX. For example, the XA1020422 is a X-Ray Angiography device.

Describe the solution you'd like
TapirX could check if the identity field starts with one of the modality strings and add a field to the output. Field name could be category.

Describe alternatives you've considered

• Post-process the output of tapirx with a script
• Post-process the output of tapirx at a REST API endpoint

EDIT: now that I think more about it, these alternatives might be better.

Additional context
Here are some examples from the wild (exact numbers are modified).

• WS1234311
• XA1458615
• US1776988
• DX2130302

Do they always match [A-Z]{2,8}[0-9]+? What do the digits mean?

It wouldn't be too taxing to add a map lookup to run after each successful message parse.

I don't know if DICOM identifiers are always in the same format. I only have one example to work with.

Of course, the map lookup is easy. The design decision is: is it worth adding a field the Asset object to represent category? Then, plumbing that through to the CSV output, REST API output, etc.
