Examples

# loading of toy-patient objects (decrease dxyz and increase beam.nb for 
# better result)
step <- 5
patient <- toy.load.patient (modality = c("rtdose", "rtstruct"), 
                             roi.name = "gizzard", dxyz = rep (step, 3), 
                             beam.nb = 3)

# Calculation of the histogram
H <- histo.from.roi (patient$rtdose[[1]], patient$rtstruct[[1]], 
                     roi.name = "gizzard", 
                     breaks = seq (0, 60, by = 1))

# DVH
DVH <- histo.DVH (H)
str (DVH)
