3D PhantomsΒΆ

These contain customisable options for the 3D Phantom Analysis. Available settings are:

  • 3D Type: Sets the default 3D phantom. Select from the list provided.

  • HU tolerance: The Hounsfield Units (HU) tolerance value for both HU uniformity and linearity.

  • Scaling tolerance: The scaling tolerance in mm of the geometric nodes on the HU linearity slice.

  • Thickness tolerance: The tolerance of the thickness calculation in mm, based on the wire ramps in the CTP404 module.

Note Not all settings have been implemented.

Note Accuracy degrades with image noise; i.e. low mAs images are less accurate.
