Biomagnetic Imaging–excerpts

 

Summary: The biomagnetic imaging program develops standards, measurement methods, and new magnetic imaging modalities for biomedical and environmental applications. Description: Biomagnetic Imaging Standards: Develops calibration structures (phantoms) and validates quantitative imaging protocols for magnetic resonance imaging (MRI); focusing on standards for cancer, brain, and multimodal imaging. Figure 1. NIST MRI system, diffusion, and breast phantoms Magnetic Nanoagents: Develops nanofabricated agents that can sense and report local properties including , agent ID, location, temperature, pH. Figure 2. (a) Microfabricated smart agents that have water proton resonance shifts to indicate particle ID, local temperature or pH. (b) Rare-earth doped iron oxide nanoparticle imaging agents. New magnetic imaging modalities: Developing ultralow field (ULF) MRI, magnetic resonance elastography, electron paramagnetic resonance imaging. www.nist.gov
