Under COVID-19, demand for tungsten alloy shielding in medical CT equipment is increasing. Many manufacturers are increasing the output of tungsten alloy shields needed for medical imaging equipment CT, such as tungsten alloy anti-scatter grids, tungsten alloy plates, tungsten alloy tubes and tungsten alloy collimators (pre-patient collimators and post-patient collimators), to support the CT examination during the epidemic of the novel coronavirus (COVID-19).

Radiation shielding tungsten alloy plate is a new type of lead-free shield. Tungsten alloy plate is mainly used for radiation protection in radiology departments such as X-ray rooms and CT rooms as it has a good shielding effect on X-rays and γ-rays.

Tungsten heavy alloy medical collimator is one of the typical radiation shielding applications of tungsten heavy alloy in the case of X-ray diagnostics. Wherein, tungsten alloy collimators are in the detector system of a medical electron linear accelerator.

W-Ni-Cu alloy protective screen, or tungsten nickel copper alloy protective screen, is a new type of lead-free medical radiation shielding screen. The biggest difference between tungsten nickel copper alloy protective screen and tungsten nickel iron alloy protective screen (W-Ni-Fe alloy protective screen) is that W -Ni-Cu alloy is non-magnetic, so that it can be used in the field sensitive to the magnetic environment, and then exert its unique anti-interference advantages.
