/*
Step-and-shoot IMRT Treatment example (multiple daily fractions).
As in the imrt2.inp file, the baseline treatment protocol calls for 15 treatment days.
Each treatment day consists of two fractions. The 0.25 Gy fraction is delivered at
8 a.m. and the 1.75 Gy fraction is delivered at 1 p.m. The patient is treated on 15
consecutive days, including weekends (see the WDO option). Fractions are delivered
as a series of 9 (high dose rate) radiation pulses separated by a 3 minute time interval
(TTO=3). The total time to deliver each fraction is approximately 24 minutes equals
(NBD-1)*TTO. The baseline 30 Gy (2 Gy per day for 15 days) treatment scenario is
then rescaled to deliver total treatment doses from 50 to 60 Gy (daily doses (both
fractions) from 3.333 Gy to 4 Gy).
The imrt2.inp and imrt3.inp examples only differ in the way the fractions are delivered.
In the imrt2.inp example, the intensity of all 9 radiation pulses (NBD=9) is the same.
In the imrt3.inp example, the intensity of radiation pulses varies. In particular,
beams 2 and 9 are deliver 100 times as much radiation as beams 1, 3, 4 5, 6, 7, and 8.
Also, the beam configurations 2 and 9 deliver the radiation at 10,000 Gy/h. The other
beams deliver radiation at 100 Gy/h.
