CaliberMRI Ships Model 340 Phantom for 4.7T, 7T and 9.4T Preclinical Scanners

CaliberMRI released the Model 340, a preclinical quantitative MRI phantom for high-field scanners, on November 10, 2026, PR Newswire reported. The Boulder, Colorado company said the phantom measures 59mm in diameter and carries NIST-traceable T1, T2 and ADC calibration solutions, with support for field strengths up to 9.4T.

What the Model 340 Phantom Contains

The Model 340 includes a resolution coupon with hole patterns in diameters from 0.4 mm to 1.2 mm, along with CaliberMRI's patented MR readable LC Thermometer. The company said the phantom complements its standard phantom line and is aimed at improving data quality, standardization, harmonization and reproducibility.

William Hollander, CEO of CaliberMRI, said the release gives sites a way to compare measurements across scanner field strengths. "We are excited to support the field with our preclinical phantom and provide an opportunity for sites to compare across field strengths - particularly in smaller coils and at 4.7T, 7T, and 9.4T," Hollander said. He added that the company is "seeing increasing interest from a broad variety of customers and collaborators implementing qMRI on preclinical scanners and on scanners with smaller bore sizes."

CaliberMRI produces integrated phantom and software platforms for quantitative MRI. Its qCal-MR automated QA/QC analysis software supports phantom scan analysis on more than 50 MRI scanner makes and models at field strengths from 64mT to 7T, according to the company. CaliberMRI said its products were developed in collaboration with the National Institute of Standards and Technology, the Radiological Society of North America and the International Society for Magnetic Resonance in Medicine, and that more than 300 papers and abstracts cite its products.
