The CATPHAN 700 is designed to address the specific testing needs of helical CT scanners.
It incorporates modifications for evaluating Z-axis variables encountered with helical scanners. The CATPHAN 700 enables the following measurements and tests:
• Slice thickness and sensitivity
• Spatial resolution (up to 21 lp/cm)
• Phantom geometry verification
• Patient alignment system verification
• Supra-slice low-contrast sensitivity
• Sub-slice low-contrast sensitivity
• Spatial uniformity
• Bed increment
• CT system background noise
• Circular symmetry
• Sensitometry (linearity)
• Matrix dimensions
• Modulation transfer function for the X, Y, and Z axes.
To enhance the phantom's functionality, various options and versions are available.
