The high-contrast spatial resolution test phantom visualizes the impact of collimation, slice width, pitch and image reconstruction algorithms.
The test pattern is a series of drill holes with varying spacing from 8.0 mm down to 0.8 mm (see table 1, right image) 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.
