 They include:
 * **RT Structure Set**, containing information related to patient anatomy, for example structures, markers, and isocenters. These entities are typically identified on devices such as CT scanners, physical or virtual simulation workstations, or treatment planning systems.
-* **RT Plan**, containing geometric and dosimetric data specifying a course of external beam and/or brachytherapy treatment, for example beam angles, collimator openings, beam modifiers, and brachytherapy channel and source specifications. The RT Plan entity may be created by a simulation workstation, and subsequently enriched by a treatment planning system before being passed on to a record and verify system or treatment device. An instance of the RT Plan object usually references a RT Structure Set instance to define a coordinate system and set of patient structures.
