Development of anthropomorphic computational phantoms at the UFPE
Brazilian Journal of Radiation Sciences, 2023 To evaluate the amount of energy deposited in radiosensitive organs and tissues of the human body, when an anthropomorphic phantom is irradiated, researchers in numerical dosimetry use the so-called exposure computational models (ECMs).

Computational phantoms, ICRP/ICRU, and further developments [PDF]
Annals of the ICRP, 2018 Phantoms simulating the human body play a central role in radiation dosimetry. The first computational body phantoms were based upon mathematical expressions describing idealised body organs. With the advent of more powerful computers in the 1980s, voxel phantoms have been developed. Being based on three-dimensional images of individuals, they offer a
