摘要：A lightweight, breathable material which has radiopaque qualities and a methodfor making the radiopaque material. In a preferred embodiment, a lightweight fabric,such as a cloth surgical mask liner () or an entire surgical mask (), is impregnated with alightweight radiopaque compound, such as a barium sulfate compound, to impart

radiopaque qualities. Impregnation of the lightweight radiopaque compound can beperformed in any number of ways, including soaking the fabric in a solution containing thelightweight radiopaque compound, using the fabric as a filter in a passing solution of thelightweight radiopaque compound, placing the fabric in a reaction chamber betweenreagent solutions whose interaction will form the lightweight radiopaque compound andimpregnating the fabric with one reagent and then exposing it to a complementaryreagent whose reaction with the first reagent will form a lightweight radiopaquecompound. To enhance the efficiency of impregnation, an additive, such as a Gum Arabicor Guar Gum adhesive, can be added to the solution containing lightweight radiopaquecompound or to the fabric itself. While a surgical mask is provided as one example, theprinciples of the invention can also be applied to a broad range of other items includingsurgical hoods, hospital gowns, gloves, partitions, patient drapes, coverings etc.
