- 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.
