Enumerated Values:​

DEFAULT​ a configured default value was used.​

MEASURED​the value was measured at the time of the other measurements.​

PROVIDED​the value was provided by an external source.​

C.33 Content Assessment Modules​

C.33.1 Content Assessment Results Module​

This Module describes the results of the assessment of a SOP Instance.​

The type of observations that are included in the results is up to the implementation. Although all observations with the Observation​ Significance (0082,0008) with value MAJOR are included, inclusion of other observation is on the discretion of the implementation.​

C.34 Procedure Protocol Modules​

This section describes Modules specific to the family of Defined and Performed Procedure Protocol IODs.​

C.34.1 CT Protocol Series Module​

The CT Protocol IODs use the General Series Module described in Section C.7.3.1, specialized by the CT Protocol Series Module,​ to describe the DICOM SeriesEntity described in Section A.1.2.3, and to define what constitutes a Series for the context of a Protocol.​

Table C.34.1-1 specifies the Attributes that describe a CT Protocol Series.​
