• DICOM provides
– A set of basic rules for all disciplines
– Discipline specific rules where necessary
– The aim has been to keep the Standard as
coherent as possible by having disciplines
interact to develop answers with as wide a
scope as possible… and to provide use cases
from representative disciplines concerned.
