C.8.21.6 Breast View Module

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

Attribute Name

Tag

Type

Attribute Description

Image Type

(0008,0008)

1

Image identification characteristics.

See Section C.8.21.6.1.1 for specialization.

View Code Sequence

(0054,0220)

1

Sequence that describes the view of the patient anatomy in this image.

Only a single Item shall be included in this Sequence.

>Include Table 8.8-1 “Code Sequence Macro Attributes” .

DCID 4014 “View for Mammography”.

>View Modifier Code Sequence

(0054,0222)

2

Sequence that provides modifiers for the view of the patient anatomy.

Zero or more Items shall be included in this Sequence.

>>Include Table 8.8-1 “Code Sequence Macro Attributes”.

DCID 4015 “View Modifier for Mammography”.

Breast Implant Present

(0028,1300)

1C

Whether or not the imaged breast contains a breast implant regardless of the visibility of a breast implant in the Pixel Data.

Enumerated Values:

YES

NO

Required if Modality (0008,0060) is MG. May be present otherwise.

Note

The value is expected to be YES for all images acquired on a breast that contains a breast implant, even when a breast implant is displaced during image acquisition.

Partial View

(0028,1350)

3

Indicates whether this image is a partial view, that is a subset of a single view of the breast.

Enumerated Values:

YES

NO

If this Attribute is absent, then the image may or may not be a partial view.

Note

This may occur when a breast is larger than the active area of the detector.

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").

Partial View Code Sequence

(0028,1352)

1C

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.

>Include Table 8.8-1 “Code Sequence Macro Attributes”

DCID 4005 “Partial View Section for Mammography”.


C.8.21.6.1 Breast View Module Attribute Description
C.8.21.6.1.1 Image Type and Frame Type

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

Defined Term

Definition

ACR MQCM Equivalent

Contrast

PRE_CONTRAST

Collected before contrast was administered.

n/a

POST_CONTRAST

Collected during or after contrast was administered.

n/a

Tomosynthesis

TOMO_PROJ

Identifies the image as a digital breast tomosynthesis projection image.

n/a

TOMOSYNTHESIS

Tomographic reconstruction from limited angle projection data.

n/a

Biopsy

TOMO_SCOUT

A localizer image set that may be used to determine positioning coordinates prior to needle positioning.

…SC

PREFIRE

An image set obtained with the biopsy needle in position prior to needle deployment.

…PRF

POSTFIRE

An image set obtained with the biopsy needle in position following needle deployment through the targeted lesion.

…POF

POSTBIOPSY

An image set obtained following tissue acquisition with the X-Ray source in the scout position.

…POB

POSTMARKER

An image set obtained following micromarker placement with the X-Ray source in the scout position.

…POM

Note

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.

Note

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

Defined Term

Definition

Tomosynthesis

GENERATED_2D

Mathematically generated 2D view.

MAXIMUM

Created through Pixel by pixel maximum operation.

MEAN

Created through Pixel by pixel mean operation.

Contrast

ADDITION

Created through Pixel by pixel addition operation.

SUBTRACTION

Created through Pixel by pixel subtraction operation.

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.

Enumerated Value

Definition

LOW_ENERGY

Low energy image.

HIGH_ENERGY
