Definition of on-axis and off-axis voxels. Left: sphere with center of coordinates. Right: voxelized slide of the sphere along its x-z plane, showing the source voxel, on-axis-voxels, and off-axis voxels.

Schematic overview of the different steps followed for calculating the VSVs.

FIG. 3.

Comparison of VSVs obtained by several authors for a voxel size of 3.0 mm as a function of the distance [DIE: Dieudonné (Ref. ), REI: Reiner (Ref. ), MIRD17: Bolch (Ref. ), LAN: Lanconelli (Ref. )]. Nuclides: I-131, Lu-177, and Y-90. For the ease of comparison we show only the data for the first 25 mm.

Tables

TABLE I.

Total energy deposited by photons and electrons from I-131, Lu-177, and Y-90 in a 10 cm-radius sphere obtained by MC simulation and with the analytic method described in this work. Data are also compared to the mean decay energy carried by the radiation according to the data from Eckerman and Endo. (See Ref. .) The electrons/photons ratios are also shown for each radionuclide.
