Get rays from beams

Description

Get rays (normalized vector directions + absolute coordinate) in the reference frame of the CT.

Usage

get.rays(beams, s = 4000, unique.rays = FALSE)

Arguments

beams	the beams data.frame
s	distance of the source from the isocenter (it uses only one virtual source).
unique.rays	Return only unique rays

Value

data frame of rays. Each ray has 6 component: a point (X,Y,Z) on the plane passing through the isocenter, and a normalized vector for the direction (xn, yn, zn).
