A disadvantage of using molybdenum for the anode material in mammography tubes is
A)less x-ray photon output.
B)increased mAs required to maintain film density.
C)increased patient dose.
D)all of the above

Question

Quizplus · Accepted Answer

Molybdenum has a high atomic number which provides better absorption characteristics for the lower energy x-rays used in mammography. However, it also has a lower thermal conductivity compared to other materials used for anodes, leading to increased heat buildup that can limit tube life and potentially compromise image quality. Additionally, the lower thermal conductivity also leads to decreased photon output, requiring higher mAs to maintain proper film density, which in turn increases patient dose. Therefore, the use of molybdenum for anode material in mammography tubes has the disadvantages of decreased photon output, increased mAs required to maintain film density, and increased patient dose.
