Syntax:
XBRT: TD4F={size of dose fraction (Gy)}
Example:
XBRT: TD4F=1.8 NTD=30 FDT=5 !1.8 Gy fraction delivered in 5 minutes (=21.6 Gy/h)
Purpose: Set the dose-fraction size
Data Type: real
Unit: Gy
Default: 2.0 Gy
Comments: The baseline radiation treatment scenario is defined by the number of treatment days (NTD) and the size of each daily fraction (TD4F). The temporal pattern of radiation deliver can be modified using the optional parameters WDO and TMX. Use the FDT keyword to specific the fraction delivery time (sugg. 1 to 20 minutes). As an alternative to the FDT method, the DFDM: keyword can be used to specify additional details related to fraction delivery. The total treatment dose (TTD) parameter can be used to automatically adjust the size of the daily dose fractions to increase or decrease the total treatment dose while preserving the overall temporal pattern of radiation delivery.
