Syntax:
SDRX: TBD={time interval between fractions}
Example:
SDRX: TBD=0.25 !Dose delivered in 15 minutes (0.25 hour)
SDRX: TBD=DD1 !Pointer to an array dose delivery times
DD1=0.01 0.25 0.5 1 2 5 12 24 / !Array of time intervals (hour)
Purpose: Set the time interval between the end of the first fraction and the start of second fraction.
Data Type: real
Unit: Gy/hour
Default: none
Comments: The time interval between fractions (the TBD parameter) equals the time of deliver (TOD) minus the 0.5*{total delivered dose (TAD)}/{dose rate (ADR)}. For an alternate method of specifying the time interval between fractions, see the TBD parameter. Fractions are delivered at the same dose rate, and fraction size is 1/2 the total delivered dose (TAD). To gain more control over dose fraction delivery, use the RADX: keyword. With the RADX: keyword, multiple fractions of different sizes can be specified and a different dose rate can be used to deliver each fraction.
