Introducing the Exclusive New Liquid Crystal MR-Readable Thermometer

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

*This product is covered by United States patent number 10,809,331.

Characterize MR image uniformity utilizing CaliberMRI’s precisely-placed fiducial reference markers

Identify geometric distortion, image uniformity, and B1 homogeneity. CaliberMRI’s 56 fiducial reference markers are placed with a precision of 150 μm (microns).
The CaliberMRI slice profile wedges are angled precisely at 10°.

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.

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