3D, 2D Low-Contrast Phantoms

For the optimization of the low-contrast resolution in all types of clinical X-ray applications

OVERVIEW

Incl. several spherical low-contrast test objects in two layers
Contrast to background -20 HU and -10 HU available

 

  • 2D Medium-Contrast Phantom

Incl. several cylindrical low-contrast test objects of different sizes (2 – 15 mm)
4 contrast steps in the phantom: -25, -50, -75 and -100 HU

 

  • 2D Low-Contrast Phantom

Incl. 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 evaluate the imaging capabilities of a 3D X-ray modality in the x/y and axial plane. The low-contrast resolution is obtained by a single spiral scan using axial images and coronal reformations. The phantoms visualize e.g. the impact of the image reconstruction.

The low-contrast inserts (spheres with varying diameter) are placed in a homogeneous tissue-equivalent background of resin. In order to mimic imaging conditions in either head or body applications, a contrast of a defined HU scale is available. Specific contrast levels are available on request!

The phantoms fit into the oval and standard Thorax Phantom.
