Catphan 700 CT Phantom

Catphan 700 CT Phantom

The Catphan 700 is an advanced CT phantom for state-of-the-art and research scanners, designed to measure full system performance. It consists of six modules in a 20 cm housing, including a 30 line pair per cm high-resolution gauge and a wave insert for resolution and geometry across the full scan area. A 360 degree rotation mount with 45 degree detents allows orientation-dependent testing. 
 
Key Features:
  • Six modules in a 20 cm housing for comprehensive CT and CBCT evaluation
  • High-resolution gauges up to 30 line pairs per cm in the CTP714 module
  • Wave insert (CTP721) for slice geometry and resolution across the scan area
  • Bead blocks for MTF and point spread function measurement
  • 360 degree rotation mount with eight detents at 45 degree intervals
  • Spring-loaded rotation lock pin for secure positioning
  • Opposed 23 degree wire and bead ramps for precise slice thickness measurement
  • Five acrylic spheres (2, 4, 6, 8, and 10 mm) and volume-averaged contrast targets
  • Solid uniformity module with no water filling or draining
  • Additional bone and lung sensitometry samples for radiotherapy planning CT
  • Integrated case mounting system with built-in level
  • Smári analysis compatibility for automated evaluation
 
Test Capabilities:
  • Sensitometry (CT number linearity) with bone and lung samples
  • Slice geometry, slice width, and slice sensitivity profile
  • High resolution up to 30 line pairs per cm
  • MTF and point spread function
  • Low-contrast sensitivity, supra-slice and subslice
  • Spatial uniformity and noise
  • Voxel resolution and geometry across the scan area
  • Orientation-dependent performance and circular symmetry
  • Phantom position verification and patient alignment system check
  • Scan incrementation
 
Applications:
  • Advanced CT and CBCT quality assurance
  • Radiotherapy CT simulation and planning image verification
  • Research on high-resolution imaging and new reconstruction methods
  • Cross-system comparison and orientation-dependent testing
  • Acceptance testing of state-of-the-art scanners
