(A) Simulated dose profile in a 10 µm muscle tissue medium [NIST material striated muscle (ICRU)] for a photon energy of 13 keV and a beam size (FWHM) of 1.40 µm. (B) Corresponding transversal dose profiles D(r) in a depth (evaluated at z = 10 µm). The transversal dose profile can be separated into two Gaussian components where one component (Gaussian 1) corresponds to the beam profile and the second component (Gaussian 2) to the broadened dose profile. The width (FWHM) of the second Gaussian is 3.33 µm. |
