Hi Adrianafolks that they might want to consider using the Patient Group Macro solution described in:
First of all, I would not refer to ancient supplements, but rather the current standard, into which Sup 122 has long since been folded, and later supplements and CPs applied, specifically relevant sections for specimen identification being:
As for TMAs, WG 26 has not done any more formal work on this, but the situation (different subjects in the same acquisition/image) is analogous to that which we addressed for mouse hotels for pre-clinical research. As such, I have suggested to TMA
- single TMA images of the entire slide with spots from different subjects (Group of Patients Identification Sequence)
- cut out images of individual spots that reference the original dummy identifier (Source Patient Group Identification Sequence)
This proposed application to TMA is hypothetical, and addresses the Patient ID, not the Specimen Identifier, and locations are relative, not absolute.
There is discussion of localization of a specific specimen (which can be listed as one of many items of Specimen Description Sequence, in which Specimen Identifier and Specimen UID are nested) in:
I don't know if anyone has any experience actually implementing Specimen Localization Content Item Sequence and TID 8004 for TMAs though.
And there has been no attempt, AFAIK, to harmonize the approach for patient (subject) and specimen identification localization yet.
If you are interested in pursuing this, I suggest that you join WG 26.
