A technique enabling the calculation of organ-level radiation dose to the fetus was developed from models of actual anatomy representing a range of gestational age, maternal size, and fetal position. Users do not need an internet connection to upload sensitive patient data to a central server. Although the United States Nuclear Regulatory Commission permits the use of the units curie, rad, and rem alongside SI units,[11] the European Union European units of measurement directives required that their use for "public health purposes" be phased out by 31 December 1985.[12]. The radiation oncology team develops the appropriate dosimetry calculations and isodose plan, builds treatment devices to refine treatment delivery, and performs any other special services required for the precision of dose delivery.
