An Imaging Phantom with
Tremendous Character

Water proficiency for T1, T2, and proton density brain qMRI standardization

Discover the CaliberMRI System Phantom

Turning MRI on its head

Premium Version

Purposeful inherent intricacy in service of providing brain qMRI consistency

One phantom. 52 spheres. Endless brain qMRI applications.

Deionized water-containing spheres for proton density mapping

The System Phantom’s proton density solution standardizes MRI scanner output so brain qMRI researchers can clearly distinguish between white and gray brain matter and image joint injuries overtime in one MRI scanner or at multiple sites.

NiCl2-containing spheres for T1 mapping

The System Phantom’s T1 spheres contain nickel chloride of varying concentrations so you can standardize T1 longitudinal relaxation so qMRI brain researchers can analyze different properties of soft tissues using characteristic T1 water signals.

MnCl2-containing spheres for T2 mapping

The System Phantom’s T2 spheres contain manganese chloride of varying concentrations so you can standardize T2 transverse relaxation so qMRI brain researchers can analyze different properties of soft tissues using characteristic T2 water signals.
