Radiation Profile 61
Appendix B: Radiation Profile
The tables below represent upper bounds on the worst case maximum power and
minimum beam filtration using a 316 stainless steel target. More specifically, the
Vanta iX was operating at either 40 kV, 100 µA w/2 mm Al filter (model VIX-CW); or,
50 kV (model VIX-MR), 80 µA, 350 µm Cu filter. Note that these beam conditions do
not represent typical use values or a combination of settings typically available from
the factory.
