The stereometric relationship Module is used to identify pairs of images that may be viewed in stereo. It is possible that the same image or Frame may be a member of multiple pairs. The images forming a pair shall be in different SOP Instances. The images forming a pair can be in different Series. All Instances referenced in this Module shall be in the same Study as the Instance in which the Module occurs.
Table C.8.18.2-1. Stereometric Relationship Module Attributes
Horizontal displacement of instrument between left and right image in mm. |
|||
Horizontal displacement of right image relative to left image in pixels for optimal display. Offset of right image to right means positive value. |
|||
Vertical displacement of right image relative to left image in pixels for optimal display. Offset of right image downwards means positive value. |
|||
Rotation of right image relative to left image in degrees for optimal display. The rotation of the right image against the left image counterclockwise is positive, rotation around the center is assumed. |

>>Include Table 10-3 “Image SOP Instance Reference Macro Attributes” |
The Referenced SOP Instance UID (0008,1155) shall not be the same as the Referenced SOP Instance UID (0008,1155) of the Right Image Sequence (0022,0022). |
||
>>Include Table 10-3 “Image SOP Instance Reference Macro Attributes” |
The Referenced SOP Instance UID (0008,1155) shall not be the same as the Referenced SOP Instance UID (0008,1155) of the Left Image Sequence (0022,0021). |
The images referenced by the Left Image Sequence (0022,0021) and Right Image Sequence (0022,0022) in a single Stereo Pairs Sequence (0022,0020) Item shall have the same values for Rows (0028,0010) and the same values for Columns (0028,0011).
The reference may be to images with a single Frame, all the Frames of images with multiple Frames, or one or more selected Frames within an image with multiple Frames. If multiple Frames are selected, the same number of Frames shall be referenced from both Sequences.
