Planar depth dose distribution for (a) 4 MeV and (b) 6 MeV electron beam, along the major axis of a 38 mm, 45º beveled IORT applicator. The lateral dose profiles at the surface and dmax for the IORT applicator conditions with (c) 4 MeV and (d) 6 MeV electron beams, respectively, and the results for the Cerrobend block conditions under (e) 4 MeV and (f) 6 MeV electron beams. The dmax dose profile for the 6 MeV electron beam shows a larger shift from surface dose profile, compared to the results for the 4 MeV electron beam. The planar depth dose distribution was created using MATLAB R2023b (The MathWorks, INC. USA).
