Filter: Whereas most xray machines use aluminum or "aluminum equivalent" to filter the xray beam to reduce unnecessary exposure to the patient, mammography uses filters that work on a different principle and are used to enhance contrast sensitivity. Molybdenum (same as in the anode) is the standard filter material. Some systems …

Xray gets attenuated on the way out by the target material itself causing a decrease in intensity g radually from the cathode to ano de direction as there is more of the target material to travel through. Therefore, the cathode side should be placed over the area of greatest density as this is the side with the most penetrating beam ...

Choice of Xray Target. The wavelength, λ, of the characteristic line giving rise to a particular transition is given by Moseley's Law: 1 / λ = c (Z σ) 2 where c and σ are constants, and Z is the atomic number of the metal used for the anode. From this equation it can seen that as the atomic number of the target increases, then the …
