Alternatively, the linac itself could make use of the object directly. An EPID can create RT Image verification images, or compare acquired images with DRRs created by the above steps. Periodically during the course of treatment, the linac or record and verify system creates Treatment Record objects, generally one for each treatment session. The above sequence illustrates just one scenario. Nevertheless, conformance statements provide a foundation to determine connectivity and assess the potential inter-operability of two products, and in some cases identify potential problems without ever having physically connected them.
Many manufacturers make their conformance statements available on the Internet.
