As with all X-rays, mammograms use doses of ionizing radiation to create images. These images are then analyzed for abnormal findings. These images are then analyzed for abnormal findings. It is usual to employ lower-energy X-rays, typically Mo (K-shell X-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for ...

Industrial Radiography uses either X-rays, produced with X-ray generators, or gamma rays generated by the natural radioactivity of sealed radionuclide sources. Neutrons can also be used. After crossing the specimen, photons are captured by a detector, such as a silver halide film, a phosphor plate, flat panel detector or CdTe detector.

EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel prize .

Anomalous X-ray scattering (MAD or SAD phasing) – the X-ray wavelength may be scanned past an absorption edge [a] of an atom, which changes the scattering in a known way. By recording full sets of reflections at three different wavelengths (far below, far above and in the middle of the absorption edge) one can solve for the substructure of ...
