MRI standards/ phantoms (Electromagnetics Division) • NIST/ISMRM MRI system phantom • NIST/USCF breast phantom • NIST/RSNA QIBA isotropic diffusion phantom (Mike Boss TU-C-12A-8 Tuesday 10:15AM) NIST’s Role in Quantitative Medical Imaging Professional Societies Universities Clinical Sites Pharma Venders NIH FDA NIST • Standard reference materials (SRMs) • Standard reference artifacts (phantoms) • Enabling traceability • Establishment of “ground truth” • Long term monitoring • Measurement development/ basic metrology research • Setting standards, most standards are consensus • Phantom mass production • Moving very fast We are good at: Not good at: NIST is a National Metrology Institute: measurement & standards
