The Narrow Beam Attenuation Curve as a Means of Assessing the Energy Imparted to a Phantom by a Low Energy X Ray Beam

Determination of x‐ray spectra from attenuation data by imposing a priori positiveness and bounded support: Theory and experimental validation

“…In this way, the author has proposed and exploited a method that considers the attenuation curve in itself as a functional description of the x-ray beam. [31][32][33][34][35] This method is well suited to the calculation, in a stable way, of radiometric and dosimetric quantities, and, in general, of generalized moments of the spectral distribution, along the lines presented in Zahrt's book. 30 The aim of the present work is to check the feasibility of an inversion method for the Laplace transform, with the a priori conditions that the solution has to be positive and that its support has to be bounded to a fixed energy range.…”
