The Catphan 500 is designed to address the specific test needs of scanners in axial mode and helicoid mode.
It incorporates the modifications to assess the variables of the Z axis encountered with the helical scanners. The Catphan 500 makes it possible to perform the following measurements and tests:

• Space resolution (up to 21 lp/cm)
• Ghost geometric verification
• Verification of the patient alignment system.
• Low contrast sensitivity "supra-slice"
• Sensitivity in low contrast "sub-slice"
• Spatial uniformity
• Bed increasing
• Background noise of the CT system
• Circular symmetry
• Sensitometry (linearity)
• Dimensions of the matrix

To increase the features of the ghost, different options and versions are available.
