The National Institute of Standards and Technology (NIST) has developed prototype calibration tools for an experimental medical imaging technique that offers new advantages in diagnosing and monitoring certain cancers and possibly other medical conditions.1

ADVERTISEMENT

NIST designed, constructed and tested two prototype phantoms for calibrating ultralow-field (ULF) magnetic resonance imaging (MRI) systems. Phantoms are widely used tools for quality control in medical imaging. They are generally objects with simple shapes but very well-defined responses to a specific type of imaging scanner. As their name implies, phantoms are stand-ins for the body, and are used to help optimize MRI machines to deliver the best possible medical images for a given type of tissue.

The NIST prototypes are the first standard calibration tools for ULF-MRI, offering a quantitative means to assess performance, validate the technique, and directly compare different experimental and clinical MRI scanners.
