### AAAA.2.3 Acme

The first part of this example is shown above in Table AAAA.2-1.

### Note

1. The author of this protocol chose to use the code for the vertex of the head rather than the skull as the basis for the plane defining the extent of the scan and reconstructions.

2. The Requested Series Description (0018,9937) is the same for both localizer acquisitions, however DICOM does not mandate series organization behavior so this does not guarantee that both localizers will be placed in the same series.

The following tables reflect the semantic contents of constraint sequences but not the actual structure of the IOD. The centered rows in italics clarify the context of the constrained Attributes that follow by indicating which sequence in the performed module contains the constrained Attribute (as specified in the Selector Sequence Pointer).
