Micro-CT Multi Disk Phantom

For testing cone-beam artifacts caused by reconstruction algorithms


  • Convenient tests of cone-beam artifacts from Micro-CT scanners
  • Standard phantom diameter 20 mm
  • Alternating 1 and 3 mm low- and high-density disks
  • Customizable


The Micro-CT Multi Disk Phantom is the test object of choice to show artifacts occurred by all kinds of approximate reconstruction algorithms.
The Micro-CT Multi Disk Phantom consists of eight high-density circular disks equally spaced 3 mm apart parallel to the axis of rotation. These disks are separated by low-density disks showing up as darker material.

Standard phantoms are scaled down from the diameter of an average human trunk (32 cm) to that of a fat mouse (32 mm).

Different dimensions and insert substances can be produced upon request.
