Micro-CT Multi Disk Phantom

For testing cone-beam artifacts caused by reconstruction algorithms

Convenient test object to check cone beam artifacts in micro-CT scanners
Includes 1 and 3 mm high- and low-density circular disks
Phantom design following Defrise

The Micro-CT Multi Disk Phantom is the test object of choice for demonstrating artifacts occurred by any kind of approximate reconstruction algorithms. The phantom consists of eight high-density circular disks evenly spaced 3 mm apart parallel to the axis of rotation. These disks are separated by low-density disks that appear as darker material.
