Table 1:
A list of organs that were measured in 1- and 10-year-old phantoms. For each organ, the number of assigned MOSFETs and the tissue weighting factors are specified based on ICRP Publication 103 and ICRP Publication 60 definitions, as well as the f-factors for the effective energy of 80, 100 and 120 kVp.
