Stream: Dicom-sr
Topic: Which FHIR resource can be used below DICOM Use Case.
Sahil Khanna (Sep 27 2021 at 10:32):
one question for my learning purpose... If you can answer..
I have a dicom file which is parsed in xml/json using a jar file
Now the request is to create FHIR resources out of it..
There is information about Measurement Group which talks about
Activity session
Tracking Identifier
Tracking unique Identifier
Algorithm Name
Algorithm Version
Algorithm Parameters
It also talks about area, length, angle of lungs structure
Do you know which fhir resource can be used to represent this information. I dont see ImagingStudy having attributes to support this.

No, you are correct, ImagingStudy does not have the attributes to support this. ImagingStudy approximates the information in a C-FIND/QIDO query.
I assume you've converted the DICOM file to standard DICOM XML or JSON, or the new "simplified" DICOM JSON. My first question is why do you need to create FHIR resources out of it? Why are the DICOM xml/json formats not sufficient? Because the model is quite different, converting DICOM SR to FHIR is likely to lead to some loss of information, or will require so many custom extensions that processing the created resources may not be any easier than processing the DICOM.
There is no standard mapping to FHIR, yet, although there is some experience being gained in this area. Your measurements are likely Observations, the algorithm information would be Device, etc.
There is an ongoing effort to define better mappings between DICOM SR and FHIR. You can see more about the current state here, and @Christopher Lindop or @Jonathan Whitby may be able to provide more insight.
