Linear quadratic model and biologically equivalent dose for single fraction treatments.
The linear quadratic model has been used to calculate the biologically equivalent dose for single fraction treatments. Our calculations suggest that for late reacting tissue, such as the brain, a single fraction of 1440 cGy is equivalent to a conventional treatment of 5000 cGy in 25 fractions.
