KeywordPositionerPrimaryAngle
Value Multiplicity1
Value RepresentationDecimal String (DS)

Position of the X-Ray beam about the patient from the RAO to LAO direction where movement from RAO to vertical is positive, if Positioner Type (0018,1508) is CARM.

See Section C.8.7.5 for further explanation if Positioner Type (0018,1508) is CARM.

See Section C.8.11.7 for explanation if Positioner Type (0018,1508) is MAMMOGRAPHIC.

Section C.8.7.5

C.8.7.5 XA Positioner Module

Table C.8-30 contains IOD Attributes that describe a c-arm positioner typically used in acquiring X-Ray Angiographic Images. The coordinate system used to track the positioner is defined in reference to the patient. The definition of coordinates with respect to the equipment is not supported. Furthermore, this Module does not describe the movement of the patient.

Note

The scope of the XA IOD is to address images produced on acquisition equipment equipped with an X-Ray source and an image Receptor positioned by what is general called a c-arm. For clinical areas other than Angiography that are using a c-arm to position the X-Ray source and image receptor (e.g., Interventional Procedures and Myelography and Biopsy/Localization), the X-Ray Angiography Image Object should be also used. Although the object is optimized for c-arm systems, it may also be used by other systems that support a similar coordinate system, such as some RF systems.

C.8.7.5.1 XA Positioner Attribute Descriptions
C.8.7.5.1.1 Positioner Motion

Positioner Motion (0018,1500) Attribute is STATIC if the imaging table moves during a multi-frame acquisition, but the X-Ray positioner do not move.

If Pixel Data (7FE0,0010) contains a single frame and a value of Positioner Motion (0018,1500) is provided, the value shall be STATIC.

Note

If the positioner undergoes translation (non-rotational movement) during the acquisition, then that motion shall be described by an opposite table motion (see Section C.8.7.4).

C.8.7.5.1.2 Positioner Primary and Secondary Angles

The definitions of Positioner Angles shall be with respect to the patient as illustrated in Figure C.8-11 and Figure C.8-12. Zero degree is referenced to the origin perpendicular to the patient's chest. The Positioner Primary Angle definition is like longitude (in the equatorial plan); the Positioner Secondary Angle definition is like latitude (in the sagittal plane). The Positioner Angle Attributes apply to the first frame of a multi-frame image. The valid range of Primary Positioner Angle is -180 to +180 degrees and the Secondary Positioner Angle range is -90 to + 90 degrees.

The Patient Plane is defined by the isocenter of the imaging device and slices through the patient such that it is perpendicular to the sagittal plane of the body. The Primary Axis of rotation is defined at the intersection of the Patient Plane and of the Sagittal Plane. The Positioner Primary Angle is defined in the transaxial plane at the isocenter with zero degrees in the direction perpendicular to the patient's chest and + 90 degrees at the patient left hand side (LAO) and -90 at the patient right hand side (RAO). The valid range of Primary Positioner Angle is -180 to +180 degrees.

The Secondary Axis is in the Patient Plane and is perpendicular to the Primary Axis at the isocenter. The Positioner Secondary Angle is defined in the Sagittal Plane at the isocenter with zero degrees in the direction perpendicular to the patient's chest. +90 degrees corresponds to the cranial direction. The Secondary Positioner Angle range is -90 to + 90 degrees.

At a 0 angle for both Primary Angle (0018,1510) and Secondary Angle (0018,1511), the patient faces the Image Intensifier or digital detector.

The Positioner Primary Angle (0018,1510) and Secondary Angle (0018,1511) apply to the first frame of a multi-frame image.

Figure C.8-11. Positioner Primary Angle


Figure C.8-12. Positioner Secondary Angle


C.8.7.5.1.3 Positioner Angle Increments

If the positioner angles change during acquisition of a multi-frame image, the Positioner Angle Increment Attributes describe the angular change per frame.

If the change in positioner angle is nominally constant for each frame, these fields may contain a single value of the average angular change per frame. Alternatively, the fields may contain a vector of offsets from the (initial) Positioner Angle Attributes, with one value for each frame in the multi-frame image. The number of values in the Positioner Angle Increment Attributes must be one, or must be equal to Number of Frames (0028,0008) in the Multi-frame Module (see Section C.7.6.6).

Note

It is permissible to generate a vector of the absolute positioner angles in the Positioner Angle Increment Attributes, and set the Positioner Primary and Secondary Angle Attributes to value 0.

C.8.7.5.1.4 Detector Primary and Secondary Angles

Detector Angles are defined in a fashion similar to the positioner angles, except that the angle of the central X-Ray beam vector is relative to the Detector Plane rather than the Patient Plane. The central X-Ray beam vector is defined as the vector from the X-Ray source through the isocenter to the detector plane. Zero degree is referenced to the normal to the detector plane pointing away from the X-Ray source. The Detector Angle Attributes apply to the first frame of a multi-frame image. The valid range of the Detector Angles is -90 to + 90 degrees.

The Primary Axis of rotation is defined along the line in the column direction of the detector plane that intersects the central X-Ray beam vector. The Detector Primary Angle is defined in the plane perpendicular to the Primary Axis of rotation at the point where the central X-Ray beam vector intersects the detector plane, with zero degrees in the direction normal to the detector plane and -90 degrees at the left hand side of the image (i.e., toward column 1) and +90 at the right hand side of the image (i.e., toward the highest numbered column). The valid range of Primary Detector Angle is -90 to +90 degrees.

The Secondary Axis is in the detector plane and is perpendicular to the Primary Axis at the intersection of the beam vector with the detector plane (i.e., it is along the row direction). The Detector Secondary Angle is defined in the plane perpendicular to the Secondary Axis at the point where the central X-Ray beam vector intersects the detector plane, with zero degrees in the direction normal to the detector plane. +90 degrees corresponds to the direction toward the top of the image. The Secondary Detector Angle range is -90 to + 90 degrees.

C.8.11.7.1 Mammography Image Attribute Descriptions
C.8.11.7.1.1 Mammography X-Ray Beam and X-Ray Beam Vector Definition

Figure C.8.11.7-1 shows the X-Ray beam for a digital mammography system. The X-Ray beam vector is defined from the Focal Spot to the center of the chest wall line of the Image Detection device.

Figure C.8.11.7-1. X-Ray Beam for a Digital Mammography System


C.8.11.7.1.2 Detector Primary and Secondary Angles

Detector Angles are defined in a fashion similar to the positioner angles, except that the angle of the X-Ray beam vector is relative to the detector plane rather than the patient plane. Zero degrees is referenced to the normal of the detector plane pointing toward the X-Ray source. The valid range of the Detector Angles is -90 to + 90 degrees.

The Primary Axis of rotation is defined along the line in the column direction of the detector plane that intersects the X-Ray beam vector. The Detector Primary Angle is defined in the plane perpendicular to the Primary Axis of rotation at the point where the X-Ray beam vector intersects the detector plane, with zero degrees in the direction normal to the detector plane and +90 in the direction of the higher numbered columns of the detector in that plane. The valid range of Detector Primary Angle is -90 to +90 degrees.

The Secondary Axis is in the detector plane and is perpendicular to the Primary Axis at the intersection of the beam vector with the detector plane (i.e., it is along the row direction). The Detector Secondary Angle is defined in the plane perpendicular to the Secondary Axis at the point where the X-Ray beam vector intersects the detector plane, with zero degrees in the direction normal to the detector plane. +90 degrees corresponds to the direction of the lower numbered rows of the detector in that plane. The Detector Secondary Angle range is -90 to + 90 degrees.

Note

Digital breast tomosynthesis projection images acquired as part of a biopsy procedure (and resulting derived images such as mathematically generated 2D) omit the _MINUS and _PLUS endings because a single digital breast tomosynthesis acquisition produces a set of projection images that replaces the _MINUS and _PLUS image pair used in conventional 2D breast biopsy imaging.

The Enumerated Values for Value 3 of contrast enhanced images are:

Table C.8-74c. Enumerated Values of Image Type (0008,0008) Value 3 for Contrast Enhanced Images

Enumerated Value

Definition

PRE_CONTRAST

Collected before contrast was administered.

POST_CONTRAST

Collected during or after contrast was administered.


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 Contrast/Bolus Module may be used to identify contrast enhanced characteristics of a biopsy and/or tomosynthesis projection or generated 2D image that is also contrast enhanced.

Value 4 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), and for mathematically generated 2D images. For other images Value 4 remains optional and implementation specific.

Enumerated Value

Definition

GENERATED_2D

Mathematically generated 2D view.

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 generated 2D 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.
