Pro-MRI is an advanced quality assurance/calibration phantom from Diagnomatic, designed for use with magnetic resonance imaging (MRI) systems. It provides tools for testing and verifying key imaging parameters – such as geometry distortion, spatial resolution, slice thickness, T1/T2 values, low contrast detection, signal-to-noise ratio (SNR), and more.

Key features and benefits

• Allows you to measure a wide range of MRI system image quality parameters, including geometry, resolution, slice thickness, low contrast, uniformity, and signal-to-noise ratio.

• Designed for both calibration ("absolute values") and daily QA (quality assurance) to ensure repeatable and reliable results on MRI machines.

• Compatible with industry standards and guidelines, including the American College of Radiology (ACR) MRI Accreditation Program and other international QC/QA reports.

• Designed with flexibility—specifications can be customized to customer needs.

Technical specifications

• Removable phantom cylinder with outside diameter approx. 220 mm (or 180 mm depending on variant) and height approx. 150 mm.

• Inner cylinder diameter approx. 204 mm (or 173 mm) and height approx. 130 mm.

• Filling: solution with 10 mmol/l nickel chloride + approx. 75 mmol/l sodium chloride.

• Resolution insert: four matrices of holes with diameters 0.8 / 0.9 / 1.0 / 1.1 mm, with hole spacing equal to hole diameter.

• Section thickness insert: PMMA plate with dimensions approx. 180 × 46 × 10 mm, has 1 mm wide and 5 mm deep spiral slots on both sides with a slope of 1:10.

• Geometric distortion insert: square matrix (10 × 10) of squares, side approximately 148 mm, thickness 10 mm.

• Low contrast insert: four polycarbonate sheets with thicknesses of 0.05 / 0.10 / 0.15 / 0.20 mm, which together with the filling solution provide contrasts of approximately 1.4%, 2.5%, 3.6% and 5.1%.

• Certifications: CE marked; complies with ACR MRI Accreditation Program, IPEM Report 80, AAPM Reports 28, 34 and 100, among others.

Areas of application

• Quality assurance and calibration of MRI systems – ensures that images meet requirements for resolution, geometry, slice thickness and other important parameters.

• Setup and documentation for MRI accreditation programs, for example at hospitals and diagnostic centers.

• Regular QA testing for MRI systems in research and clinical environments, where repeatability and traceability to standards are crucial.

• Integration with QA software and logging for documentation and traceability of test results.
