A previously presented algorithm for the reconstruction of bremsstrahlung spectra from transmission data has been implemented into MATHEMATICA ® . Spectra vectorial algebra has been used to solve the matrix system A * F = T . The new implementation has been tested by reconstructing photon spectra from transmission data acquired in narrow beam conditions, for nominal energies of 6, 15, and 25 MV. The results were in excellent agreement with the original calculations. Our implementation has the advantage to be based on a well‐tested mathematical kernel. Furthermore it offers a comfortable user interface.
