Table C.8.21.6-1 specifies the Attributes of the Breast View Module, which describe the view of a digital breast tomosynthesis image.
Table C.8.21.6-1. Breast View Module Attributes
Image identification characteristics. See Section C.8.21.6.1.1 for specialization. |
|||
Sequence that describes the view of the patient anatomy in this image. |
|||
>Include Table 8.8-1 “Code Sequence Macro Attributes” . |
|||
Sequence that provides modifiers for the view of the patient anatomy. |
|||
>>Include Table 8.8-1 “Code Sequence Macro Attributes”. |
|||
Whether or not the imaged breast contains a breast implant regardless of the visibility of a breast implant in the Pixel Data. Required if Modality (0008,0060) is MG. May be present otherwise. |
|||
Indicates whether this image is a partial view, that is a subset of a single view of the breast. If this Attribute is absent, then the image may or may not be a partial view. If this Attribute is present, its value shall be NO if there is a View Modifier Code Sequence (0054,0222) Item of value (399163009, SCT, "Magnification") or (399055006, SCT, "Spot Compression"). |
|||
Sequence that describes the portion or section of the breast captured in a partial view image. One or two Items shall be included in this Sequence. See Section C.8.11.7.1.3. Required if Partial View (0028,1350) is present with a value of YES. |
|||
In addition to the requirements specified in Section C.8.21.1.1.1 Image Type and Frame Type, the following Defined Terms are specified for Value 3 of Image Type (0008,0008) and Frame Type (0008,9007):
Table C.8.21.6-1a. Defined Terms of Image Type (0008,0008) Value 3 for Contrast Enhanced, Tomosynthesis and Biopsy
There is no need for _MINUS or _PLUS because a single digital breast tomosynthesis acquisition produces a projection and/or reconstruction image set that replaces the _MINUS and _PLUS image pair used in conventional 2D breast biopsy imaging (see Section C.8.11.7.1.4).
If more than one characteristic (biopsy, tomosynthesis, contrast enhanced) applies to an image, Value 3 shall contain the biopsy image type. If biopsy is not involved, Value 3 shall contain the tomosynthesis image type.
For example, Attributes of the Enhanced Contrast/Bolus Module may be used to identify contrast enhanced characteristics of a biopsy and/or tomosynthesis image that is also contrast enhanced.
Value 4 shall be NONE except for applicable contrast enhanced images, mathematically generated 2D images and other tomosynthesis reconstructions. The following Defined Terms are specified for Value 4 of Image Type (0008,0008) and Frame Type (0008,9007). For additional Defined Terms see Section C.8.16.1.4.
Table C.8.21.6-1b. Defined Terms of Image Type (0008,0008) Value 4 for Contrast Enhanced and Tomosynthesis
If more than one characteristic (contrast enhanced, tomosynthesis) applies to an image, Value 4 shall contain the contrast enhanced image type. If contrast enhanced is not involved, Value 4 shall contain the tomosynthesis image type.
Value 5 shall be present for images acquired using contrast enhanced digital X-Ray imaging of the breast, but may be empty if none of the Defined Terms applies. For non-contrast images Value 5 remains optional and implementation specific.
A recipient may use the different values for biopsy, tomosynthesis and contrast views to determine how to display them, for example in hanging protocols:
