The Catphan 700 is designed to approach the specific test needs of CT Helicoid scanners.
It incorporates the modifications to assess the variables of the Z axis encountered with the helical scanners. The Catphan 700 makes it possible to perform the following measurements and tests:
• Cutting and sensitivity thickness
• Spatial resolution (up to 21 lp/cm)
• Geometric verification of the ghost
• Verification of the patient alignment system.
• Sensitivity in low contrast "supra-slice"
• Sensitivity in low contrast "sub-slice"
• Spatial uniformity
• Bed increment
• Basic noise of the CT system
• Circular symmetry
• Sensitometry (linearity)
• Dimensions of the matrix
• Modulation transfer function for axes x, y and z
to increase the ghost functionalities, different options and versions are available.
