Standardize T1 and T2 Weighted MRI

CaliberMRI is pioneering the field of quantitative MRI with NIST-traceable contrast mimics. Each sphere contains ground truth human tissue brain mimics consistent with what MRI specialists expect from CaliberMRI.

NiCl2-containing spheres for T1 mapping between 20 ms and 1900 ms, 3.0 T at 20°C

The CaliberMRI Premium 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 between 5 ms and 550 ms, 3.0 T at 20°C

The CaliberMRI Premium System Phantom’s T2 spheres contain manganese chloride of varying concentrations so users can standardize T2 transverse relaxation to ultimately analyze different properties of soft tissues.

Proton density spheres for PD mapping between 5% and 100%

The CaliberMRI Premium System Phantom’s proton density 5%-100% array standardizes proton density in relation to typical tissue water content, in addition to precisely estimating the signal-to-noise ratio (SNR).

Introducing the Exclusive New Liquid Crystal MR-Readable Thermometer

Expand the temperature range capabilities of MRI standardization with the one-of-a-kind MR-readable thermometer

MRI standardization just got even easier with the integration of the CMRI patented LC MR-Readable Thermometer, developed in collaboration with NIST.1 Now qMRI advancers can standardize between 15°C and 24°C while simultaneously scanning the Essential System Phantom.

Compare & Contrast Premium vs. Essential Temperature Features

Contains CMRI's patented LC MR-Readable Thermometer for temperature standardization between 15°C and 24°C while scanning.

Achieve MR image uniformity utilizing CMRI’s precisely-placed fiducial reference markers

Identify geometric distortion, image uniformity, and B1 homogeneity. CMRI’s 56 fiducial reference markers are placed with a precision of 150 μm (microns) so users can obtain the premium insight into scanner distortions.

Compare & Contrast & Premium vs. Essential Distortion Features

56 fiducial markers containing copper sulfate surrounded by a polycarbonate plastic sphere.

Enhance slice resolution and evaluate alignment

The CMRI slice profile inclination and declination wedges are angled precisely at 10° for advanced slice profile accuracy.

Compare & Contrast Premium vs. Essential Slice Resolution Features

Inclination and declination wedges angled precisely at 10°.

Expand your understanding of scan quality with the ultimate precision of the CMRI resolution insert

The CaliberMRI resolution insert minimizes misalignment on and off scan axis when processed with the recommended resolution MRI protocol.

Compare & Contrast Premium vs. Essential Resolution Features

Two sets of 4×4 resolution insert patterns offset by 10°. Includes an array of holes with one set of diameters ranging from 0.4 mm to 0.8 mm, and another set of diameters ranging from 0.6 mm and 1 mm.
