getEQD2: 2Gy fractions biologically equivalent dose (EQD2)

Description

Calculate dose in 2Gy fractions biologically equivalent dose according to the linear-quadratic model.

Usage

getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)

Arguments

D
Total dose. If NULL, nf must be given.
fd
Fractional dose.
fn
Number of fractions. If NULL, D must be given.
ab
alpha/beta ratio for the relevant tissue.

Value

  • The (vector of) EQD2 value(s)

Details

EQD2 is a special case of isoeffective dose with fractional dose d2=2, see getIsoEffD.
