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 Coded Entry 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, which includes NONE. Value 4 is not permitted to be empty or absent.
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 or absent 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. See examples in Table C.8.21.6-1d.
The entry "empty" in the table indicates that the value is present with zero length and a preceding delimiter (e.g. "Tomosynthesis thick reconstructed slices pre-contrast" has one empty value at the end and would be expressed as ORIGINAL\PRIMARY\TOMOSYNTHESIS\MAXIMUM\). Other empty or non-empty values may follow an empty value.
The entry "-" in the table indicates that the value is not present and neither is its preceding delimiter (e.g. "Tomosynthesis thin reconstructed slices" has one absent value at the end and would be expressed as ORIGINAL\PRIMARY\TOMOSYNTHESIS\NONE). No other values may follow an absent value.
