Density scaling artifacts in dosimetry calculations

Quality assurance dosimetry often requires the comparison of measured doses with those calculated by a treatment‐planning system for phantoms of density other than 1.000 g/cm(3). The presence of an artifact in the Pinnacle3 treatment‐planning system can lead to systematic errors in such cases.(a) Th...

Sumario:Quality assurance dosimetry often requires the comparison of measured doses with those calculated by a treatment‐planning system for phantoms of density other than 1.000 g/cm(3). The presence of an artifact in the Pinnacle3 treatment‐planning system can lead to systematic errors in such cases.(a) These errors are also present, although reduced in magnitude, in heterogeneous media.
