MRI Multipurpose Phantom




The MRI Multipurpose Phantom monitors the overall performance of an MRI system. The parameters that can be measured include: slice thickness, slice orientation, interslice gap, magnetic field homogeneity, radio frequency signal uniformity, spatial resolution in positive and negative contrast, and modulation transfer function. The phantom can also be used to evaluate quadrature setting, baseline correction, aspect ratio, and single T1 and T2 values.

The phantom is constructed of non-magnetic materials. It is 9 inches in diameter, with two inserts, and is designed to be filled with an MRI signal-producing solution. One insert is a series of concentric conic sections. The other insert is made up of five sections: one for positive contrast, two for slice evaluation, one for MTF evaluation, one for T1 and T2 evaluations.

A void between the sections provides a fully flooded area for signal uniformity.

Key Features
The MRI Multipurpose Phantom provides a comprehensive range of tests in one compact unit. Tests include:

  • Slice thickness
  • MTF evaluation
  • Spatial resolution
  • RF signal uniformity
  • Magnetic field homogeneity
  • And many others
