C.8.21.2.3 Breast Tomosynthesis Contributing Sources Module (Current)

Table C.8.21.2.3-1 specifies the Attributes of the Breast Tomosynthesis Contributing Sources Module, which describe Breast Tomosynthesis Contributing Sources. 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 Instance.

Note

The intention of this Module is to supply acquisition information without the need to have access to all the source projection images.

Table C.8.21.2.3-1. Breast Tomosynthesis Contributing Sources Module Attributes

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 Table 10-13 “General Contributing Sources Macro Attributes”
>Include Table 10-14 “Contributing Image Sources Macro Attributes”
>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. Note Due to the length limit imposed by the VR of this Attribute, a full-length serial number may need to be truncated. If truncated, the remaining string value should be as unique as possible within the local (site) context of use, and hence perhaps retain the tail rather than the head of the string. The full-length value can be encoded in X-Ray Detector ID (0018,9371).
>X-Ray Detector ID	(0018,9371)	3	Identifier of the physical X-Ray detector. This might be the serial number. Note If the value in Detector ID (0018,700A) is truncated due to VR length limitations, this Attribute may be used to convey the full-length value.
>Date of Last Detector Calibration	(0018,700C)	1	The date on which the detector used to acquire this image was last calibrated.
>Time of Last Detector Calibration	(0018,700E)	1	The time at which the detector used to acquire this image 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 Section 10.7.1.3 for further explanation of the order of the Values. Note This may not be the same as the Imager Pixel Spacing (0018,1164), and should not be assumed to describe the stored image.
