A four‐parameter Laplace transform pair model, which accurately reconstructs an experimental bremsstrahlung spectrum from attenuation data, is presented. Computed spectral values with both aluminum and copper attenuators generally agree with experimental 70‐kVp data to better than 2%. Reconstructed spectra at other kVp's also show good agreement with published data.
