Get rays (normalized vector directions + absolute coordinate) in the reference frame of the CT.
get.rays(beams, s = 4000, unique.rays = FALSE)
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 |
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).
