Investigation of inter‐source and intra‐source spectral variations in an electronic brachytherapy source using spectral measurements and Monte Carlo simulations

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background The Xoft electronic brachytherapy source is commonly used to treat superficial lesions and tumors located at shallow depths. However, uncertainties in material composition and geometry, mainly arising due to the manual assembly of the x‐ray tube components, contribute to inter‐source variability in the tube output spectrum.
