New NIST Standard Reference Material to Help Calibrate Hospital CAT Scanners

Caption

Standard Reference Material 2088 makes it possible to link CAT scans to the International System of Units for the first time. The SRM -- a collection of five blocks of polyurethane foam of different densities, shown here in front of its delivery case -- allows scans to be tied to measurement units important for diagnosing lung disease.
