Table C.7.6.14-1 specifies the Attributes of the Acquisition Context Module, which describes the conditions present during data acquisition.

This Module shall not contain descriptions of conditions that replace those that are already described in specific Modules or Attributes that are also contained within the IOD that contains this Module.


  1. If this SOP Instance is a Multi-frame SOP Instance, each Item of the Acquisition Context Sequence (0040,0555) may be configured to describe one frame, all frames, or any specifically enumerated subset set of frames of the Multi-frame SOP Instance. Previously, Referenced Frame Numbers (0040,A136) was used to enumerate which frames were described, but its length was limited, so it has been replaced by Referenced Frame Number (0008,1160). Similarly, applicability to a subset of Segments or Waveform Channels may be specified.
