Bureau of Radiological Health.].   "Updates fundamentals and applications of all modes of x-ray spectrometry, including total reflection and polarized beam x-ray fluorescence analysis, and synchrotron radiation induced x-ray emission. Promotes the accurate measurement of samples while reducing the scattered background in the x-ray spectrum."5/5(2). Handbook of mammographic x-ray spectra / By Thomas R. Fewell, Ralph E. joint author. Shuping and United States. Bureau of Radiological Health. Division of Electronic Products. Abstract. Mode of access: Internet Topics.   The corrected x-ray spectra are compared against tabulated x-ray spectra measured under nearly identical conditions. Results indicate that the current device is capable of producing accurate relative x-ray spectral measurements in the energy region from 12 keV to 40 keV, which represents most of the screen-film mammography energy range.

  The handbook's editor, Dr. Paolo Russo, has over 30 years’ experience in the academic teaching of medical physics and X-ray imaging research. He has authored several book chapters in the field of X-ray imaging, is Editor-in-Chief of an international scientific journal in medical physics, and has responsibilities in the publication committees. The most accurate x‐ray spectral shape, related with the minimal HVL value, and high photon fluence for measured spectra was found with the spectrometer aligned according to the proposed method. The HVL values derived from both simulated and measured x‐ray spectra differ at most and % for two mammography devices evaluated in this study.   Fewell T R and Shuping R E Handbook of Mammographic X-ray Spectra (Springfield: NTIS) HEW publication (FDA) 79 () pp Goodwin P N Physics in Canada 32 McMaster W H The Handbook of Physics and Chemistry 58th Edition (Cleveland, OH: CRC) UCRL p E ff.   The X-ray scattering and absorption in the air gap between the X-ray source and the phantom has been neglected, in order to increase the computational efficiency of the simulation. This assumption leads to a minor overestimation, of about %, of the surface dose, due to some low-energy photons that are actually absorbed in the air and not in.

Constant potential mammographic x-ray spectra .   Mammography X-Ray Tube Target materials consist of three main types. • Molybdenum • Specialized Tungsten • Rhodium • Molybdenum – the best material to be used in mammography, – allows production of low energy spectrums of radiation – low kVp (kVp) • Tungsten and Rhodium are used for higher beam needs, in dense breast tissues. This detector system was designed to simultaneously measure the X-Ray tube peak potential (kVp), and to characterize the mammographic X-Ray tube spectrum.
