Displacer

Displacer is a tool dedicated to visualize geometric inaccuracies of your MRI acquisition. It combines information from gradient non-linearities, determined using special geometry phantoms, and patient- and acquisition-specific inaccuracies in your MR images. This tool was specifically developed for MRI-guided radiotherapy, which has very demanding constraints on the geometrical accuracy of the MR images.

Main features:

  • Fully automated geometric inaccuracy visualization on top of your MR image.
  • Both online and offline execution.
  • Provides confidence that your MR acquisition are showing the correct anatomical position
