  1. SD standard deviations, Fx fraction, BOT beam on time, LOT leaf open time, Large large fields including cranial spinal irradiation or treatment fields with lymph nodes
  2. *Dynamic fraction is the ratio of the incomplete projections that were replaced with planned data to compensate for insufficient detector data from the dynamic jaw technique
