Collection(name)

Interface for a collection of concepts, such as SNOMED-CT, or a DICOM CID.

Code(value, scheme_designator, meaning[, ...])

Namedtuple for representation of a coded concept consisting of the actual code value, the coding scheme designator, the code meaning (and optionally the coding scheme version).

Usage#

Individual Code values can be accessed via either their scheme (such as SCT) or the DICOM CID:

>>> from pydicom.sr import codes
>>> codes.SCT.Transverse
Code(value='62824007', scheme_designator='SCT', meaning='Transverse', scheme_version=None)
>>> codes.CID4.Cornea
Code(value='28726007', scheme_designator='SCT', meaning='Cornea', scheme_version=None)

A list of available attribute keywords for each scheme or CID is available via dir():

>>> dir(codes.CID6)
['Coronal', 'FiveChamber', 'FourChamber', ... ]
