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.
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
