Adult Male and Female Reference Computational Phantoms (ICRP Publication 110)

抄録

The purpose of the present paper is to review ICRP Publication 110 entitled “Adult reference computational phantoms”.¹⁾ In its recent recommendations, the ICRP adopted these computational phantoms for the forthcoming update of organ dose coefficients for internal and external radiation sources. The phantoms are based on medical image data of real persons and are consistent with the information given in ICRP Publication 89 on the reference anatomical and physiological parameters for both male and female subjects. The reference voxel models were constructed after modifying the voxel models of two individuals whose body height and mass closely resembled the reference data. The organ masses of both models were adjusted to the ICRP data on the adult Reference Male and Reference Female, without significantly altering their realistic anatomy. The ICRP publication describes the methods used for this process and the characteristics of the resulting voxel phantoms. Furthermore, the applications of these phantoms intended by ICRP and ICRU are indicated, and the phantoms' limitations are highlighted. The phantoms' technical descriptions as well as graphical illustrations of conversion coefficients for some external and internal exposures are presented in a series of Annexes to ICRP Publication 110. In addition to ICRP Publication 110, the present paper shortly characterises intermediate versions of the reference computational phantoms that are referred in the literature.
