CaliberMRI – diffusion phantom for quantitative MRI
The Diffusion NIST/QIBA Phantom is CaliberMRI’s platform for supporting diffusion-weighted imaging standardisation and quantification, including longitudinal and multi-site comparison when used within locally validated protocols.
Typical use
Suitable for MRI, research and QA/QC teams that need a physical reference for ADC measurements, technical variation tracking across systems and documented diffusion performance checks.
Key points
- The official page describes the platform as including the NIST/QIBA Diffusion Phantom and companion qCal-MR QC automation software.
- The source states development in collaboration with NIST, NIH and RSNA/QIBA, and also references QIBA, NIST and NCI in the platform context.
- The phantom uses PVP human tissue mimic solutions to support interpretation of water movement in MRI.
- CaliberMRI lists a 194 mm diameter for compatibility with most MRI scanners.
- Includes ten 30 mL vials with aqueous PVP solutions from 10% to 50% w/w for ADC measurements.
- Includes three 30 mL distilled-water vials for reference and 5 mL water vials used as fiducial markers.
- The official page references an LC MR-readable thermometer for temperature compensation from 15 °C to 24 °C during scanning.
- qCal-MR software can compare MRI measurement outputs with NIST-traceable values and share technical studies.
