Web28 de fev. de 2024 · Beryllium is commonly used in mammography (which use low-energy photons) as it provides very little filtration. Other types of x-ray generally use aluminum, copper or tin. Filtration reduces x-ray intensity, but not the maximum energy of the x-ray beam spectrum. Web28 de nov. de 2006 · The adjustment of a beam-limiting device to limit an X-ray field at the detector to about 2.5 cm squares was done. The X-ray exposures were made on the detector for three timer settings. In most cases, the exposure technique factors used were 80 kV and 200 mA.
