Differences between kilovoltage and electron therapy While both modalities are suited for superficial treatments, the mechanism of dose deposition is different, resulting in clinically significant differences in the features of…
Chapter 8). Maximum dose is deposited at the surface and the 90% dose level will be approximately 2 mm deep for a 60 kV beam up to 10 mm deep at 220 kV. The…
