Table C.8.19.6-2. X-Ray Field of View Macro Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Field of View Sequence | (0018,9432) | 1 | Sequence containing the field of view for this frame. Only a single Item shall be included in this Sequence.
>Field of View Shape | (0018,1147) | 3 | Shape of the Field of View, that is the image pixels stored in Pixel Data (7FE0,0010). Enumerated Values: RECTANGLE ROUND HEXAGONAL
>Field of View Dimension(s) in Float | (0018,9461) | 3 | Dimensions in mm of the Field of View, that is the image pixels stored in Pixel Data (7FE0,0010). If Field of View Shape (0018,1147) is: RECTANGLE: row dimension followed by column. ROUND: diameter. HEXAGONAL: diameter of the circle circumscribing the hexagon.
>Field of View Origin | (0018,7030) | 1C | Offset of the TLHC of a rectangle circumscribing the Field of View, i.e., the image pixels stored in Pixel Data (7FE0,0010) before rotation or flipping, from the TLHC of the physical detector area measured in physical detector pixels as a row offset followed by a column offset. See Section C.8.11.4.1.1 for further explanation. Required if X-Ray Receptor Type (0018,9420) is present and equals DIGITAL_DETECTOR. May be present otherwise.
>Field of View Rotation | (0018,7032) | 1 | Clockwise rotation in degrees of Field of View, i.e., the image pixels stored in Pixel Data (7FE0,0010), relative to the physical detector. Enumerated Values: 270 180 90 0 See Section C.8.11.4.1.1 for further explanation.
>Field of View Horizontal Flip | (0018,7034) | 1 | Whether or not a horizontal flip has been applied to the Field of View, i.e., the image pixels stored in Pixel Data (7FE0,0010), after rotation relative to the physical detector as described in Field of View Rotation (0018,7032). Enumerated Values: NO YES See Section C.8.11.4.1.1 for further explanation.
>Field of View Description | (0018,9433) | 3 | Manufacturer defined description of the field of view selected during acquisition.
