Der Pencil-Beam-Algorithmus ist eine von Bestrahlungsplanungssystemen in der Strahlentherapie genutzte Dosiskalkulationstechnik für der Strahlendosis im Gewebe.
(ICRP 127):
A beam of radiant energy concentrated in an approximately conical or cylindrical portion of space of relatively small diameter.
Pencil beam (algorithm)
One of the dose calculation techniques for radiotherapy treatment planning. It assumes that any beam incidenting the patient is actually a conglomeration of lots of ‘pencil beams’, and the dose at any point of interest is given as the superposition of all the pencil beams.
Pencil beam (in scanning irradiation technique)
Dose is delivered by superposing ‘pencil beams’ from an accelerator on the target by controlling the beam path three-dimensionally.
Herr Willner Übersetzt.
