CaliberMRI – mini diffusion phantom for MRI
The CaliberMRI Mini Diffusion Phantom is the Model 138 member of the CaliberMRI diffusion family, using the same mimics listed for the Diffusion NIST/QIBA Phantom in a smaller spherical format.
Typical use
Suitable for MRI, research and QA/QC teams that need a compact physical reference for ADC measurement tracking, diffusion protocol support and documented technical comparison, while validating local compatibility and use.
Key points
- The official page identifies the product as the Mini Diffusion Phantom and states that it includes the same mimics as the CaliberMRI NIST/QIBA Diffusion Phantom.
- The public Model 138 spec sheet lists a 170 mm spherical shell designed to fit most MRI scanners and head coils.
- Includes ten 15 ml vials with traceable aqueous PVP solutions in concentrations from 10% to 50%.
- Includes three 15 ml vials and three 5 ml vials with HPLC water for reference.
- The spec sheet lists a ten-element MR-readable LC thermometer for temperature compensation from 15 °C to 24 °C.
- The supplier states compatibility with qCal-MR QA/QC software.
- The sheet states nominal values taken at 3T and 20 °C.
