This topic provide an example of a common parsing scenario used in field mapping expressions in Source Manager. Field mappings are used to extract and manipulate study data.
In this scenario, one of the identifiers is contained in a different data element of the image header than it should be in. For example, maybe the accession number is passed to the system in the referring physician name element (0008,0090) instead of in the accession number element (0008,0050).
In this example, use one of the following expressions:
| Element to extract | Mapping to use |
|---|---|
| Accession number | getdicomstring( 0x080090 ) |
| Accession number | getdicomstring( hex( '524432' )) |
