Tube filter (rt), английский
A filter that can be attached to the x-ray tube housing.
Composite filter (rt), английский
A filter of two or more materials chosen so that the longer wavelengths of a beam are readily absorbed, and within this range undesirable radiation transmission is avoided. the materials are usually arranged so that the second material filters secondary radiation produced in the first material and so on. a particular example is the “thoraeus filter” which consists of 0.44 mm of tin, 0.25 mm of copper and i mm of aluminum in this order in the beam of radiation.
