10.10 general Contributing Sources MACRO

Table 10-13 contains IOD Attributes that describe the general characteristics of the contributing sources used to create a new SOP Instance.

Table 10-13 GENERAL CONTRIBUTING SOURCES MACRO ATTRIBUTES

Attribute Name Tag Type Attribute Description
Contributing SOP Instances Reference Sequence (0020,9529) 1C A sequence that identifies the contributing SOP Instances. Required if this SOP Instance is created from other DICOM SOP Instances. Note: The attribute is absent in the case where the sources used to create this SOP Instance are not SOP Instances, e.g., a volume that was directly generated by an acquisition system. One or more Items shall be included in this sequence.
>Study Instance UID (0020,000D) 1 Unique identifier for the Study of the Contributing SOP Instances.
>Referenced Series Sequence (0008,1115) 1 Sequence of Items each of which includes the Attributes of one Series. One or more Items shall be included in this sequence.
>>Series Instance UID (0020,000E) 1 Unique identifier of the Series containing the referenced Instances.
>>Series Number (0020,0011) 2 A number that identifies this Series.
>>Referenced Instance Sequence (0008,114A) 1 Sequence of Items each providing a reference to an Instance that is part of the Series defined by Series Instance UID (0020,000E) in the enclosing Item. One or more Items shall be included in this sequence.
>>>Include ‘SOP Instance Reference Macro' Table 10-11
>>>Instance Number (0020,0013) 2 A number that identifies this instance.
Manufacturer (0008,0070) 2 Manufacturer of the equipment that produced the sources.
Manufacturer's Model Name (0008,1090) 1C Manufacturer’s model name of the equipment that produced the sources. Required if present and consistent in the contributing SOP Instances.
Device Serial Number (0018,1000) 1C Manufacturer’s serial number of the equipment that produced the sources. Required if present and consistent in the contributing SOP Instances.
Software Versions (0018,1020) 1C Manufacturer’s designation of software version of the equipment that produced the sources. See Section C.7.5.1.1.3. Required if present and consistent in the contributing SOP Instances.
Acquisition DateTime (0008,002A) 1C The time the acquisition of data that resulted in sources started. The value shall be the start date and time of the first contributing SOP Instance of the group specified by the Contributing SOP Instances Reference Sequence (0020,9529). Required if present and consistent in the contributing SOP Instances. Note: The Acquisition DateTime may be created by combining the values of Acquisition Date (0008,0022) and Acquisition Time (0008,0032) attributes in the contributing SOP Instances.
Station Name (0008,1010) 1C User defined name identifying the machine that produced the sources. Required if present and consistent in the contributing SOP Instances.
Operators’ Name (0008,1070) 1C Name(s) of the operator(s) supporting the Series. Required if present and consistent in the contributing SOP Instances.
Operator Identification Sequence (0008,1072) 1C Identification of the operator(s) supporting the Series. One or more items shall be included in this sequence. If more than one Item, the number and order shall correspond to the value of Operators’ Name (0008,1070), if present. Required if present and consistent in the contributing SOP Instances.
>Include ‘Person Identification Macro’ Table 10-1
Protocol Name (0018,1030) 1C User-defined description of the conditions under which the Series was performed. Required if present and consistent in the contributing SOP Instances. Note: This attribute conveys series-specific protocol identification and may or may not be identical to the one presented in the Performed Protocol Code Sequence (0040,0260).
Performed Protocol Code Sequence (0040,0260) 1C Sequence describing the Protocol performed for the Procedure Step creating the sources. One or more Items shall be included in this Sequence. Required if present and consistent in the contributing SOP Instances.
>Include ‘Code Sequence Macro’ Table 8.8-1 No Baseline Context ID is defined.
Acquisition Protocol Name (0018,9423) 1C User defined name of the protocol used to acquire this image. Required if present and consistent in the contributing SOP Instances.

Note: The attributes at the first level of the General Contributing Sources macro contain information that is common to all the Referenced SOP Instances included in the Contributing SOP Instances Reference Sequence. This allows to not duplicate information when the contributing instances are single-frame objects and/or when they are in different Series with the same protocol and manufacturer information.

Typically the General Contributing Sources macro is invoked from inside another sequence. Therefore, if the "common" attributes of the macro are different among the Referenced SOP Instances, like different acquisition prococols, software versions etc., the invoking sequence will contain several items.
