3D, 2D Low Contrast Phantoms

For measuring the low-contrast resolution in CT and Cone-Beam CT

  • 3D Low Contrast Phantom 
    • D100 compatible
    • Includes several spherical low contrast inserts arranged in two planes 
    • 2 different contrast levels relative to the background 
      • QRM-10109: 3D Low Contrast Phantom (-10 HU)
      • QRM-10110: 3D Low Contrast Phantom (-20 HU)
  • QRM-10100: 2D Medium-Contrast Phantom
    • D100 compatible
    • Includes several cylindrical medium-contrast test objects of different sizes (2-15 mm)
    • 4 contrast steps in the phantom: -25, -50, -75 and -100 HU
  • QRM-10112: 2D Low-Contrast Phantom
    • D100 compatible
    • Includes several cylindrical low-contrast test objects of different sizes (5 - 15 mm)
    • Contrast to background -20 HU and -10 HU in one phantom

The phantoms are ideally suited for the evaluation of the imaging capabilities of 3D X-ray imaging modalities (e.g. CT or Cone-Beam CT). The contrast resolution is obtained by a single spiral scan using axial images (QRM-10109, QRM-10110, QRM-10100, QRM-10112) and coronal reformations (QRM-10109, QRM-10110). The phantoms visualize the impact of all, scan, image reconstruction, and display parameters.

The low or medium-contrast inserts (spheres/rods with varying diameters) are located within the cylindrical body of homogeneous tissue-equivalent material. 

The phantoms fit into the Thorax, Abdomen and Oval Body Phantom.
