getEQD2 {DVHmetrics} | R Documentation |
Calculate dose in 2Gy fractions biologically equivalent dose according to the linear-quadratic model, assuming a homogeneous dose distribution within the volume.
getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)
## Default S3 method:
getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)
## S3 method for class 'DVHs'
getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)
## S3 method for class 'DVHLst'
getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)
## S3 method for class 'DVHLstLst'
getEQD2(D=NULL, fd=NULL, fn=NULL, ab=NULL)
D |
Default: Total dose. If |
fd |
Fractional dose. If |
fn |
Number of fractions. If |
ab |
alpha/beta ratio for the relevant tissue. If |
EQD2 is a special case of isoeffective dose calculation with fractional dose d2=2
, see getIsoEffD
. The calculation assumes a homogeneous dose distribution within the volume.
Default method: A data frame with variables EQD2
, fractDose
, ab
.
If D
is some kind of DVH
object, the same kind of object is returned with the individual dose values converted to EQD2.
