Catphan 605 CT Phantom

Catphan 605 CT Phantom

The Catphan 605 is a compact, cost-effective CT phantom for measuring the maximum performance of multi-slice and other state-of-the-art CT scanners. It uses two modules within a 20 cm housing to cover slice geometry, sensitometry, MTF, low-contrast detectability, and uniformity. Its enhanced capability for thin slices and high-resolution imaging suits modern multi-slice systems. 
 
Key Features:
  • Two modules in a compact 20 cm housing for a focused, efficient QA suite
  • Slice geometry ramps with both wire and bead options for slice width measurement
  • Enhanced precision for thin slices and high-resolution scanners
  • MTF measurement using wire or bead point sources
  • Volume-averaged sphere contrast targets for low-contrast evaluation
  • Solid-cast uniformity module for spatial uniformity and noise testing
  • Sensitometry targets for CT number linearity, including bone-equivalent materials
  • Solid-cast construction with no water filling, draining, or water-source variability
  • Smári cloud-based analysis included for automated evaluation and trend tracking
 
Test Capabilities:
  • Sensitometry (CT number linearity)
  • Slice geometry, slice sensitivity profile, and slice width with wire and bead ramps
  • Pixel (matrix) size and circular symmetry
  • Phantom position verification and patient alignment system check
  • Scan incrementation
  • MTF using wire or bead point sources
  • Contrast targets using volume-averaged spheres
  • Spatial uniformity and noise (precision)
 
Applications:
  • Routine CT quality assurance on multi-slice scanners
  • Acceptance testing and commissioning
  • Traveling physicist and multi-site CT evaluations
  • Scanner performance trending and multi-scanner comparison
  • Budget-conscious QA programs requiring a focused test suite
 
Specifications:
  • Housing diameter: 20 cm
  • Modules: CTP682 (slice geometry and sensitometry) and CTP729 (uniformity and noise)
  • Sensitometry materials: Teflon, bone-equivalent (50% and 20% hydroxyapatite), Delrin, acrylic, polystyrene, LDPE, PMP, lung foam, air, and water (small vial)
  • Slice geometry: three sets of opposed ramps
  • Analysis: Smári cloud-based software included
