(0040,0555) Acquisition Context Sequence
2
A sequence of repeating items that describes the conditions present during the acquisition of an Image. Zero or more items may be included in this sequence.
(0040,A043) >Concept Name Code Sequence
1C
A concept that constrains the meaning of (i.e. defines the role of) the Observation Value. The “Name” component of a Name/Value pair. This sequence shall contain exactly one item. Required if a sequence item is present.
(0040,A136) >Referenced Frame Numbers
1C
References one or more frames in a Multi-frame SOP Instance. The first frame shall be denoted as frame number one. Required if Acquisition Context Sequence (0040,0555) is sent and this SOP Instance is a Multi-frame SOP Instance and the values in this sequence item do not apply to all frames.
(0040,A30A) >Numeric Value
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a set of one or more numeric values. Required if Concept Name Code Sequence (0040,A043) is present and the value it requires (implies) is a set of one or more integers or real numbers. Shall not be present otherwise.
(0040,08EA) >Measurement Units Code Sequence
1C
Units of measurement. Only a single Item shall be permitted in this Sequence. Required if a sequence item is present and Numeric Value (0040,A30A) is sent. Shall not be present otherwise.
(0040,A121) >Date
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a date. Note: The purpose or role of the date value could be specified in Concept Name Code Sequence (0040,A043). Required if Concept Name Code Sequence (0040,A043) is present and the value it requires (implies) is a date. Shall not be present otherwise.
(0040,A122) >Time
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a time. Note: The purpose or role of the time value could be specified in Concept Name Code Sequence (0040,A043). Required if Concept Name Code Sequence (0040,A043) is present and the value it requires (implies) is a time. Shall not be present otherwise.
(0040,A123) >Person Name
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a Person Name. Note: The role of the person could be specified in Concept Name Code Sequence (0040,A043). Required if Concept Name Code Sequence (0040,A043) is present and the value it requires (implies) is a person name. Shall not be present otherwise.
(0040,A160) >Text Value
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a Text Observation Value. Required if Date (0040,A121), Time (0040,A122), and Person Name (0040,A123) do not fully describe the concept specified by Concept Name Code Sequence (0040,A043). Shall not be present otherwise.
(0040,A168) >Concept Code Sequence
1C
This is the Value component of a Name/Value pair when the Concept implied by Concept Name Code Sequence (0040,A043) is a Coded Value. This sequence shall contain exactly one item. Required if a sequence item is present and Date (0040,A121), Time (0040,A122), Person Name (0040,A123), Text Value (0040,A160), and the pair of Numeric Value (0040,A30A) and Measurement Units Code Sequence (0040,08EA) are not present.
