PET-CT Phantom

The PET-CT Phantom™ includes 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.

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 are for registration
• The outer 2" OD micro cylinder is for comparing attenuation region to non attenuation region
• The 6" ring is for contrast solution
• Research
