An algorithm utilizing a two‐dimensional polynomial power functions least squares fit has been applied to the calculations of TAR in the case of CO‐60 teletherapy and TMR in the case of an 8MV SL75/10 linear accelerator giving less than ±1/2% errors respectively between calculated and measured values. The TAR and TMR algorithms are used as subroutines in pocket sized and table top programmable calculators or computers and thus provide rapid calculation of treatment time or monitor units as well as given dose.
