Dear FHIR community,
I am interested in linking FHIR resources to external NIfTI resources . NIfTI is widely used by researchers in preclinical neuroimaging to encode MRI, EEG, ECG, MEG… This evidently overlaps DICOM, but the simplicity of NIfTI makes it extremely appealing to researchers.
My question is: What is the recommended way to associate a FHIR “Patient” module with an external NIfTI study stored on a network drive (i.e. outside of the FHIR server)?
I don’t think that the “Media” module is appropriate, as NIfTI can encode non-image/video/sound data (such as EEG or ECG). Likewise, the “ImagingStudy” is not adapted, as it is specific to DICOM.
I was therefore considering of using the “DocumentReference” module, with an “content / attachment” field that would point to the URL of the NIfTI. This “DocumentReference” would in turn be linked to an “Observation” module through the “derivedFrom” field.
Is this the expected solution? If so, is there a full example of such a setup? I thank you much in advance!
