Catphan 600 CT Phantom

Catphan 600 CT Phantom

The Catphan 600 is a modular CT phantom for maximum performance characterization of multi-slice CT scanners. It consists of five modules in a 20 cm housing, covering slice geometry, sensitometry, high resolution, low-contrast detectability, and uniformity. Its expanded sensitometry set makes it suitable for radiotherapy CT sensitometry, and its integrated mount with built-in leveling supports fast, repeatable daily QA on any scanner. Supplied by Meditronix Corporation in India.

Key Features:
  • Five modules in a compact 20 cm housing: CTP404, CTP591, CTP528, CTP515, and CTP486
  • Eight sensitometry targets for CT number linearity, suited to radiotherapy CT
  • Opposed 23 degree wire ramps for precise slice thickness measurement
  • Bead ramps for slice width, slice sensitivity profile, and table incrementation
  • High-resolution gauge up to 21 line pairs per cm
  • Five acrylic spheres (2, 4, 6, 8, and 10 mm) for subslice contrast evaluation
  • Solid-image uniformity module that avoids water-tank variability
  • Gantry angle verification of up to 10 degrees using ramp length ratios
  • Universal mount with built-in level to reduce table artifacts
  • Smári cloud-based analysis for automated evaluation and trend tracking
 
Test Capabilities:
  • Slice geometry, slice width (thin and thick), and sensitivity profile
  • Sensitometry and CT number linearity
  • Pixel (matrix) size and circular symmetry
  • High resolution, MTF, and point spread function
  • Low-contrast sensitivity, supra-slice and subslice
  • Spatial uniformity and noise
  • Phantom position verification and patient alignment system check
  • Scan incrementation
 
Applications:
  • Daily and periodic multi-slice CT quality assurance
