A test object that allows the complex focal trough of the panoramic x-ray unit to be quantified, as well as the capacity for spatial resolution testing using line-pair test patterns (available separately) and contrast resolution testing using a dedicated test insert.
This allows full assessment of parameters affecting image quality. Can be used in film and digital systems.

Measure:
• Limiting spatial resolution
 • Contrast resolution
• Quantification of the focal trough and image layer
