PET CT Phantom™

  • PET CT Phantom™
  • PET CT Phantom™


Main Features:

• The PET-CT Phantom™ includes internal structures (three rods and six spheres) which when imaged with both modalities can demonstrate how accurately the two image sets are aligned.
• In addition, a single sample of radioactive water is attenuated by water, bone, and CT contrast material (as well as air only) to determine how accurately the CT-based PET attenuation correction works.
• Spheres are fillable from outside the closed cylinder

Main Applications:

• Acceptance testing of PET/CT and SPECT/CT systems
• Routine quality evaluation of PET/CT and SPECT/CT Systems
• Evaluation of new image fusion software
• Evaluation of new attenuation correction algorithms
• Aluminum tubes are for registration
• The outer 2” OD micro cylinder is for comparing attenuation region to non-attenuation region
• The 6” ring
