Required if present and consistent in the contributing SOP Instances. Note: This value is traditionally referred to as Source Image Receptor Distance (SID).
>Distance Source to Isocenter (0018,9402) 1C Distance from source to isocenter in mm. Required if present and consistent in the contributing SOP Instances.
>Focal Spot (0018,1190) 1C Nominal focal spot size in mm used to acquire this image. Required if present and consistent in the contributing SOP Instances.
>Filter Type (0018,1160) 1C Type of filter(s) inserted into the X-Ray beam (e.g. wedges). See Attribute Description in Section C.8.7.10 for Defined Terms. Note: Multiple type of filters can be expressed by a combination, e.g., BUTTERFLY+WEDGE. Required if present and consistent in the contributing SOP Instances.
>Filter Material (0018,7050) 1C The X-Ray absorbing material used in the filter. May be multi-valued. See Attribute Description in Section C.8.7.10 for Defined Terms. Required if present and consistent in the contributing SOP Instances.
>Filter Thickness Minimum (0018,7052) 1C See Attribute Description in Section C.8.7.10 . Required if present and consistent in the contributing SOP Instances.
>Filter Thickness Maximum (0018,7054) 1C See Attribute Description in Section C.8.7.10 . Required if present and consistent in the contributing SOP Instances.
