A Monte Carlo Study on the PTW 60019 MicroDiamond Detector.

Hartmann GH, Zink K

Data on the output correction factor of the PTW microDiamond for small photon beam dosimetry can be found in a variety of papers. Referring either to measurements or to Monte Carlo (MC) calculations, they show substantial disagreements particularly at very small fields. This work reports results of a further MC study aiming at a better understanding of how specific properties of the MicroDiamond detector are influencing its output correction factor and whether this can explain at least some of the disagreements.
