bin.sum: Sum of two binaries

Description

The bin.sum function creates a "volume" class object of "binary" modality, representing the sum (logical OR) of two binary objects.

Usage

bin.sum(vol1, vol2, alias = "", description = NULL)

Value

Returns a "volume" class object of "binary" modality (see espadon.class for class definitions), with the same grid as vol1 and vol2, sum of vol1 and vol2.

Arguments

vol1, vol2

"volume" class objects of "binary" modality.

alias

Character string, $alias of the created object.

description

Character string, describing the created object. If description = NULL (default value), it will be set to paste (vol1$object.alias, "+", vol2$object.alias).

Examples

# loading of toy-patient objects (decrease dxyz for better result)
step <- 4
patient <- toy.load.patient (modality = c("ct", "rtstruct"), roi.name = "eye",
                             dxyz = rep (step, 3))
CT <- patient$ct[[1]]
S <- patient$rtstruct[[1]]

z.leye<- S$roi.info$Gz[S$roi.info$roi.pseudo == "lefteye"]


# 'left eye' et 'right eye' binaries
bin.left.eye <- bin.from.roi (CT, struct = S, roi.sname = "lefteye",
                              alias = "left eye", verbose = FALSE)
bin.right.eye <- bin.from.roi (CT, struct = S, roi.name = "righteye",
                               alias = "right eye", verbose = FALSE)
bin.eyes <- bin.sum (bin.left.eye, bin.right.eye, alias = "eyes")

display.plane (CT, top = bin.eyes, struct = S, roi.sname = "eye",
               view.coord = z.leye, legend.shift = -90 ,
               interpolate = FALSE)
