PET-CT Phantom™
T
• Complies with NEMA 2012 Standard • Simulation of whole-body imaging using PET and camera-based coincidence imaging techniques • Evaluation of reconstructed image quality in whole-body PET and camera-based coincidence imaging • Determination of the coincidence count rate characteristics in brain and cardiac imaging • Evaluation of the relationship between true coincidence count rate and radioactivity • Determination of the address errors caused by address pile up • Evaluation of the count loss correction scheme
SPECIFICATIONS:
he 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 – Research
SPECIFICATIONS:
Main Cylinder: Interior length of phantom: 180 mm Fillable spheres (5) inner diameter: 10 mm, 13 mm, 17 mm, 22 mm, and 28 mm. Distance from sphere plane to inside wall: 70 mm Volume of empty cylinder: 9.7 liters Main Cylindrical insert dimension: Outside diameter: 51 mm Length: 180 mm Top Cylinder: Cylinder outside diameter: ~5.1 cm Cylinder inside diameter: ~4. cm Cylinder inside height: ~8.2 cm Cylinder outside height: ~12.0 cm Volume of empty cylinder: 408 cm2 Three Aluminum Tubes: One 5 inch long: ~1.7 cc Two 7 inch (ea): ~ 2.5 cc Stepped Bone Ring: Pre-filled with liquid bone composition, not to be opened The volumes for the bone ring are: Outer volume: 15.6 cu inch: ~256 cc Inner volume: 6.7 cu inch: ~110 cc
