Syntax:
XBRT: FDT={fraction delivery time in minutes}
Example:
XBRT: TD4F=1.8 NTD=30 FDT=5 !1.8 Gy fraction delivered in 5 minutes (=21.6 Gy/h)
Purpose: Set fraction delivery time
Data Type: real
Unit: minute
Default: n/a (must be specified)
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). Instead of using FDT to specify the fraction delivery time, the DFDM: keyword can be used to specify the fraction delivery method in more detail. 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.
