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.

Magnetic Nanoagents: Develops nanofabricated agents that can sense and report local properties including , agent ID, location, temperature, pH.

New magnetic imaging modalities: Developing ultralow field (ULF) MRI, magnetic resonance elastography, electron paramagnetic resonance imaging.
