Purpose/Objective:
To use fractional integral target dose to obtain the fraction of energy absorbed by the prostate from integral dose, which is an indication of “radiation delivery efficiency” in brachytherapy. Also to introduce a parameter that shows the fraction of excess energy absorbed in the prostate. Those parameters can be used to aid the clinical choice of isotopes.
