Dose 2016

Dose through kernel integration - 1

Double exponential, tabulated over depth

The dose to the central axis from a circular field with radius R (and laterally uniform energy fluence) can be calculated as

D =

In the same way, the dose to the central axis from a square field, with side s , can be calculated by employing the equivalent circle with R =0.561 · s .

This is the PB dose calculation in Oncentra TPS (formely Helax-TMS)
