Table 4.

(a) Mean and standard deviation (n = 40 dosimetry analyses) of OAR organ masses, TIACs and ADs calculated using Dosimetry Toolkit + OLINDA/EXM® V1.0 and PLANET® Dose with LDM and DK and density correction. (b) Relative differences (%) of the organ mass values and TIACs between PLANET® Dose and Dosimetry Toolkit + OLINDA, DTK, Dosimetry Toolkit
