Collimator leaves must be constructed of highly attenuating materials such as:

Explanation:
X-ray collimator leaves are designed to block stray photons and shape the beam, so they must be highly effective at absorbing X-rays. Materials with a high atomic number and high density do this best because they provide strong attenuation across diagnostic-energy photons. Lead fits this role well: its high Z (82) and high density make it very effective at absorbing X-rays, reducing leakage and keeping the beam tightly confined. Iron, aluminum, and copper have lower atomic numbers or densities, so they don’t attenuate as efficiently in the diagnostic energy range and would allow more stray photons to pass. That’s why lead is the preferred material for collimator leaves.
