Pencil-Beam-Algorithmus
Aus Glossar Strahlenschutz
The “pencil beam” algorithm is dose calculation technique. It assumes that any collimated photon beam hitting (incident) on the patient is actually a conglomeration of lots of smaller, narrow “pencil beams”. Each of these pencil beams has a central axis ray along which it deposits some dose. The dose deposition pattern varies with the intensity and the spectrum of the beam that is incident on the patient.
