The X-Ray Filters in Enhanced RDSR are described in TID 10046 “Filtration” which references the X-Ray Source to which they are applied. Detailed X-Ray Filters characteristics are described in TID 10055 “Attenuator Characteristics” and it covers the technical description of the filters (e.g., Material, Type and Thickness). Note that TID 10055 is also used to describe any other attenuator such as patient support.

If the 3D position and shape of the X-Ray Filter is known, a 3D model of the filter can be referenced in TID 10051 “Beam Position”, which includes the Transformation Matrix for the referenced filter 3D model into the Source Coordinate System of the referenced X-Ray Source. If the X-Ray Filter position is unknown and no model can be supplied, the X-Ray Filter is assumed to cover the complete Field of View of the X-Ray beam.

The position of the collimator blades in Enhanced RDSR is encoded as a shape (i.e., POLYGON or ELLIPSE) in TID 10049 “Radiation Field Area”, which references the X-Ray Source to which this collimator is applied. The shape is defined in the Source Coordinate System of the referenced X-Ray Source. When multiple shapes are encoded for the same X-Ray Source, the actual radiation field surface is the intersection of the shapes.

TID 10054 “Procedure Characteristics” encodes the X-Ray Grid to indicate if an anti-scatter grid was used by describing the related grid type (see CID 10017). A value of "No grid" is available to indicate it was removed or it is not supported by the equipment.

Other attenuators not defined in the Source Coordinate System are described in TID 10047 “Attenuators” and their characteristics are described in TID 10055 “Attenuator Characteristics”. Similarly to the X-Ray Filters, if the 3D position and shape of the attenuator is known, a 3D model of the attenuator can be referenced in TID 10052 “Attenuator Position”, which includes the 3D model of the Attenuator and the related Transformation Matrix to transform the Attenuator coordinates to the RDSR Reference Coordinate System. If the Attenuator position is unknown and no model can be supplied, the Attenuator is assumed to cover the complete Field of View of the X-Ray beam.
