Photon (x-ray, gamma-ray, bremsstrahlung) mass attenuation coefficients, mu/rho, are among the most widely used physical parameters employed in medical diagnostic and therapy computations, as well as in diverse applications in other fields such as nuclear power plant shielding, health physics and industrial irradiation and monitoring, and in x-ray crystallography. This review traces the evolution of this data base from its empirical beginnings totally derived from measurements beginning in 1907 by Barkla and Sadler and continuing up through the 1935 Allen compilation (published virtually unchanged in all editions up through 1971-1972 of the Chemical Rubber Handbook), to the 1949 semi-empirical compilation of Victoreen, as our theoretical understanding of the constituent Compton scattering, photoabsorption and pair production interactions of photons with atoms became more quantitative. The 1950s saw the advent of completely theoretical (guided by available measured data) systematic compilations such as in the works of Davisson and Evans, and by White-Grodstein under the direction of Fano, using mostly theory developed in the 1930s (pre-World War II) by Sauter, Bethe, Heitler and others. Post-World War II new theoretical activity, and the introduction of the electronic automatic computer, led to the more extensive and more accurate compilations in the 1960s and 1970s by Storm and Israel, and by Berger and Hubbell. Today's mu/rho compilations by Cullen et al, by Seltzer, Berger and Hubbell, and by others, collectively spanning the ten decades of photon energy from 10 eV to 100 GeV, for all elements Z= 1 to 100, draw heavily on the 1970s shell-by-shell photoabsorption computations of Scofield, the 1960s coherent and incoherent scattering computations of Cromer et al, and the 1980 computations of electron-positron pair and triplet computations of Hubbell, Gimm and Øverbø, these names being representative of the vast legions of other researchers whose work fed into these computations.

“…The inherent interpretive flexibility of the approach should ensure that it can impact across several fields of research: materials science is an obvious beneficiary as the structure, texture and composition of functional objects and systems can be displayed more meaningfully; medical (tissue) imaging should also benefit through the wide range of potential signals. [5][6][7] The absence of any rotary scanning can also be a distinct advantage since it means that complex systems (e.g. those with connected services and feeder/exit pipes such as continuous flow systems 26 ) can be tomographically examined in situ without complication.…”

“…There are various non-destructive mapping methods that utilise coherent white X-ray scattering for different applications: examples are strain tensor mapping, 1,2 baggage-security scanning, 3 and biological tissue characterisation; [4][5][6][7][8] we also note recent progress in monochromatic tomography aimed towards detecting low concentrations of crystalline material. 9 However, it is the development of Tomographic Energy Dispersive Diffraction Imaging [10][11][12][13][14][15][16][17][18] that has brought about the prospect of a more general non-destructive mapping whereby a variety of structural features can be revealed within bulk objects containing crystalline and non-crystalline phases; the method has been applied to both static and dynamic systems.…”

Reconstructive colour X-ray diffraction imaging – a novel TEDDI imaging method

Tomographic Energy-Dispersive Diffraction Imaging (TEDDI) enables a unique non-destructive mapping of the interior of bulk objects, exploiting the full range of X-ray signals (diffraction, fluorescence, scattering, background) recorded. By analogy to optical imaging, a wide variety of features (structure, composition, orientation, strain) dispersed in X-ray wavelengths can be extracted and colour-coded to aid interpretation. The ultimate aim of this approach is to realise real-time high-definition colour X-ray diffraction imaging, on the timescales of seconds, so that one will be able to 'look inside' optically opaque apparatus and unravel the space/time-evolution of the materials chemistry taking place. This will impact strongly on many fields of science but there are currently two barriers to this goal: speed of data acquisition (a 2D scan currently takes minutes to hours) and loss of image definition through spatial distortion of the X-ray sampling volume. Here we present a data-collection scenario and reconstruction routine which overcomes the latter barrier and which has been successfully applied to a phantom test object and to real materials systems such as a carbonating cement block. These procedures are immediately transferable to the promising technology of multi-energy-dispersive-detector-arrays which are planned to deliver the other breakthrough, that of one-two orders of magnitude improvement in data acquisition rates, that will be needed to realise real-time high-definition colour X-ray diffraction imaging.

“…Rayleigh scattering has been considered as a non-invasive diagnostic tool [24] in biological and medical applications for photon energies of 1-150 keV [25]. Usually in medical applications, such as when destroying malignant diseases, the aim is to reduce the amount of photon scattering [26] as scattered pho- Figure 1.1: Diagrams of the single-photon scattering processes with schematic atomic levels of hydrogen shown for reference.

A pseudostate method for computing photon-atom scattering cross-sections

A computational method is developed for photon-atom scattering cross-sections given by the p • A interaction, which dominates scattering at low frequencies. Our method is simple and intuitive, and has the advantage of being extremely adaptable-it can be extended to higher-order scattering processes and applied to any atom. The scattering cross-sections calculated in this thesis provide a more complete picture of the photon-atom interaction than is currently available, which is useful for high-precision atomic, molecular and optical (AMO) experiments and has applications in astrophysics and spectroscopy.
