Which material is most commonly used in mammography tubes to optimize image quality?

Molybdenum is the most commonly used material in mammography tubes due to its optimal properties for breast imaging. It has a specific atomic number and a low energy threshold that allows it to produce X-rays with optimal contrast for the soft tissue composition of breast tissue. When X-rays are generated, the energy levels produced by molybdenum are well-suited to create high-quality images without over-penetrating the tissue, which is crucial for detecting abnormalities.

Molybdenum's characteristic X-ray energies align well with the needs of mammography, ensuring that the resultant images provide the necessary details to assess breast tissue effectively. This makes it preferable over other elements, particularly because it minimizes the radiation dose to the patient while maximizing image quality.

While tungsten, rhodium, and silver have their applications in radiography and other imaging modalities, they are not as specifically tailored for the unique requirements of mammography as molybdenum, which has been established as the gold standard in this field.
