intersection
intersection
The set of elements that are members of both of two specified sets.
Notes
In set theory, the intersection of sets ** A** and B refers to all elements that are in both set A and set B.
In SNOMED CT, the intersection of two _subsets _of concepts consists of all concepts that are members of both subsets.
Examples
The following expression constraint language defines the set of concepts that in the intersection subtypes of 85562004 | Hand| and members or the 723264001 | Lateralizable body structure reference set| . The "AND" instruction indicates a union between the sets defined by constraints on either side of that instruction.
< 85562004 |Hand| AND ^ 723264001 |Lateralizable body structure reference set|
