7.14.8 RT Treatment Phase

An RT Course may be divided into multiple RT Treatment Phases. Each RT Treatment Phase represents a period of time during which a defined number of RT Treatment Fractions are delivered by RT Radiation Sets in order to reach a specific treatment goal (see Section 7.14.9 and Section 7.14.10).

An RT Treatment Phase also defines the chronological relationship between RT Radiation Sets that are concurrently and/or subsequently treated.
