3D Spatial Resolution Phantom

For the visual evaluation of spatial resolution in CT and Cone-Beam CT

  • 2 different versions available
    • QRM-10111 3D Spatial Resolution Phantom (stand-alone)   
    • QRM-10101 3D Spatial Resolution Phantom, D100 
  • Evaluate spatial resolution in-plane and sagittal CT images
  • Provides several hole patterns in two planes

The high-contrast spatial resolution test phantom visualizes spatial resolution axial and sagittal plane of dedicated CT protocols and image reconstruction algorithms. The test pattern is a series of drilled holes with varying diameter and spacing from 4.0 mm down to 0.4 mm (see Specifications) allowing for an order of magnitude in spatial frequency. With spiral/helical CT, evaluating both axial images and coronal reformations, spatial 3D resolution can be tested by a single scan.
