This section describes the Breast Tomosynthesis Contributing Sources Module. The attributes in this Module specify the overall characteristics of one or more source images that were used to create a Breast Tomosynthesis Image SOP Class instance. Table C.184.108.40.206-1 contains the IOD Attributes that describe Breast Tomosynthesis Contributing Sources.
Note: The intention of this module is to supply acquisition information without the need to have access to all the source projection images.

|Attribute Name||Tag||Type||Attribute Description|
|Contributing Sources Sequence||(0018,9506)||1||A sequence that describes characteristics of the sources that are used to create a derived SOP Instance. One or more Items shall be included in this sequence.|
|>Include ‘General Contributing Sources Macro’ Table 10-13|
|>Include ‘Contributing Image Sources Macro’ Table 10-14|
|>Detector Type||(0018,7004)||1||The type of detector used to acquire this image. Defined Terms: DIRECT = X-Ray photoconductor SCINTILLATOR = Phosphor used STORAGE = Storage phosphor|
|>Detector ID||(0018,700A)||1||The ID or serial number of the detector used to acquire this image.|
|>Date of Last Detector Calibration||(0018,700C)||1||The date on which the detector used to acquire this image as identified in Detector ID (0018,700A) was last calibrated.|
|>Time of Last Detector Calibration||(0018,700E)||1||The time at which the detector used to acquire this image as identified in Detector ID (0018,700A) was last calibrated.|
|>Detector Element Spacing||(0018,7022)||1||Physical distance between the center of each detector element, specified by a numeric pair: row spacing value (delimiter) column spacing value in mm. See 10.7.1.3 for further explanation of the value order. Note: This may not be the same as the Imager Pixel Spacing (0018,1164), and should not be assumed to describe the stored image.|
