PET-CT Phantom™

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.

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.

The Phantom is used for:

  • 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 evaluate registration
  • Outer 2" OD micro cylinder compares attenuation region to non attenuation region
  • 6" ring studies contrast solution
  • Research
