getEUD: Generalized equivalent uniform dose (gEUD)

Description

Calculate generalized equivalent uniform dose (gEUD). May be based on EQD2.

Usage

getEUD(x, EUDa, EUDfd=NULL, EUDab=NULL, ...)

## S3 method for class 'DVHs':
getEUD(x, EUDa, EUDfd=NULL, EUDab=NULL, ...)

## S3 method for class 'DVHLst':
getEUD(x, EUDa, EUDfd=NULL, EUDab=NULL, ...)

## S3 method for class 'DVHLstLst':
getEUD(x, EUDa, EUDfd=NULL, EUDab=NULL, ...)

Arguments

x

One cumulative DVH (object of class DVHs, multiple cumulative DVHs from one patient with multiple structures (object of class DVHLst), or multiple cumulative DVHs from many patients, each with multiple structures (object of class

EUDa

Exponential parameter a.

EUDfd

If gEUD should be based on EQD2: Fraction dose.

EUDab

If gEUD should be based on EQD2: alpha/beta ratio for the relevant tissue.

...

Ignored. Used to catch additional arguments passed from getMetric.

Value

• A data frame with variables EUD, patID, and structure.
