Under epidemic of novel coronavirus pneumonia, demand for 3D printing tungsten alloy radiation shield for applications in CT device is increasing. In order to support the demand for CT examination during the epidemic of COVID-19, some manufacturers are increasing the output of 3D printing tungsten alloy anti-scattering grids required for medical imaging equipment such as CT scanners, according to reports.

Studies have shown that tungsten alloy is the optimum choice for producing radiation shields as it has higher density and better ionizing radiation absorption characteristics than lead. Also, tungsten alloy is non-toxic and environmentally friendly while lead is toxic. Tungsten alloy anti-scattering grid is used in CT equipment to absorb and shield harmful scattered radiation and more accurately introduce X-rays into the photodiode, thereby significantly improving the quality of CT images and protecting patients from excessive ionizing radiation. In fact, in addition to the anti-scattering grid, there are many other tungsten alloy radiation shields on CT equipment, including tungsten alloy tubes, tungsten alloy plates, and so on.
