Pro MRI Phantom Kit Assess Magnetic Resonance Imaging Distortion

The Pro-MRI Phantom is an exceptionally accurate phantom to assess magnetic resonance imaging distortion caused mainly by the nonlinearity of the magnetic gradients even in large field of view.

Pro MRI Phantom Kit Overview

The Pro-MRI Phantom is an exceptionally accurate phantom to assess magnetic resonance imaging distortion caused mainly by the nonlinearity of the magnetic gradients even in large field of view. Tests supported include:

  • Geometric Distortion • Spatial Resolution • Slice thickness and position • Interslice Gap
  • Estimate of Image Bandwidth • Low Contrast Detectability • Image Uniformity
  • Signal-to-Noise Ratio (SNR) • Physical and Electronic Slice Offset • Landmark positions
  • Versatile phantom for QC to ACR, AAPM and IPEM guidelines (220 or 180mm in diameter).
  • When empty, the grid-air interface provides good contrast under CT. The phantom images well with all CT techniques and MRI sequences, including T1 weighted, T2 weighted, 3D Time of Flight, MPRAGE and CISS sequences.
