Computational Phantoms of the ICRP Reference Male and Reference Female
Computational models of the human body – together with radiation transport codes – have been used for the evaluation of organ dose conversion coefficients in occupational, medical and environmental radiation protection. During the last two decades, it has become common practice to use voxel models that are derived mostly from (whole body) medical image data of real persons instead of the older ...
متن کاملOrgan doses from environmental exposures calculated using the ICRP Reference Male and Reference Female voxel phantoms
In its recent recommendations the ICRP adopted two voxel models of an adult male and an adult female to be used for the forthcoming update of organ dose conversion coefficients. These voxel models are representative of an average population, i.e. they resemble the ICRP reference anatomical data with respect to their external dimensions and their organ masses and were constructed for this purpos...
متن کاملConstruction of Taiwanese Adult Reference Phantoms for Internal Dose Evaluation
In the internal dose evaluation, the specific absorbed fraction (SAF) and S-value are calculated from the reference phantom based on Caucasian data. The differences in height and weight between Caucasian and Asian may lead to inaccurate dose estimation. In this study, we developed the Taiwanese reference phantoms. 40 volunteers were recruited. Magnetic resonance images (MRI) were obtained, and ...
متن کاملHistological Aspects of Cerebrum and Cerebellum in Adult Male and Female Mongoose (Herpestes edwardsii)
BACKGROUND: Mongooses are small carnivores residing in different regions from Africa to southeast Asia. The Indian gray mongoose (Herpestes Edwardsii) is one of the mongoose species that is mostly found in southern Asia particularly India and the south of Iran. Anatomical studies on the animal's brain have always been of interest to the scientist due to its high importance in various branches o...
متن کاملExtension of RPI-adult male and female computational phantoms to obese patients and a Monte Carlo study of the effect on CT imaging dose.
Although it is known that obesity has a profound effect on x-ray computed tomography (CT) image quality and patient organ dose, quantitative data describing this relationship are not currently available. This study examines the effect of obesity on the calculated radiation dose to organs and tissues from CT using newly developed phantoms representing overweight and obese patients. These phantom...
