K. Griffin, S. Dewji, T. Cuthbert, and a. Lee “A comparison of age-dependent organ depth distributions: stylized versus voxel phantom series”, Poster. 3rd International Conference on Dosimetry and its Applications, Lisbon, Portugal, 27-31 May 2019.
The main parameter influencing organ dosimetry from external irradiation is the organ’s position below the surface of the body. Initially, models of the human body were defined through surface equations (stylized phantoms) and have now been advanced by more anatomically realistic models based on medical patient images (voxel phantoms). The impact of this shift in modelling has been studied rigorously through comparisons of external dosimetry simulation results. For photon irradiation, differences in organ dose between the series are often interpreted as differences in organ depth and positioning. This work, however, represents the first effort to quantify the differences in organ depths between a stylized and voxel phantom series.
