/*
  Step-and-shoot IMRT Treatment example (multiple daily fractions).

  In this example, the 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 = (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).

  Compare to the imrt1.inp and imrt3.inp sample file.
