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.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.
Extended Oval PET Phantom - Turkington
The Extended Oval PET Phantom is designed to simulate the distribution of radioactivity throughout the long body torso. It consists of a set of two 40 cm long cylinder sections with an oval shaped cross section. A single 40 cm section fills the axial FOV of a large camera. The Phantom allows placement of optional internal containers to simulate radioactive distribution in various optional organ inserts.
Cardiac Insert
-
Evaluation of cardiac ECT data
-
Evaluation of attenuation and scatter
-
Simulates normal and abnormal myocardial uptake
-
Solid inserts simulate transmural and non-transmural cold abnormalities
This insert provides a multi function simulation of the left ventricle, and can be used to evaluate SPECT imaging of cold defects within “myocardium.” Two solid acrylic sectors are supplied with the insert, each 1cm thick and 2 cm long. These non filling defects may be placed at various positions within the ventricle wall, (anterior or posterior). The long axis of the ventricle is adjustable from 30 to 60 degrees from the long axis of the cylinder.
PET Phantom - NEMA/IEC 2000
The NEMA/IEC 2000 is ideal for whole body PET.
-
Complies with NEMA 2001 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.
The NEMA/IEC 2000 PET Phantom consists of a body phantom, a fillable lung insert and an insert with six various size spheres that are fillable from the outside of the phantom. The cylindrical insert is filled with styrofoam beads. The user fills the chamber with liquid. It is designed in accordance with the recommendations by the International Electrotechnical Commission (IEC) and modified by the National Electrical Manufacturers Association (NEMA.) It is recommended for use in the evaluation of reconstructed image quality in whole body PET imaging.
PET Sensitivity Phantom - NEMA 2001
The phantom consists of six concentric tubes that slide into each other. The innermost tube is fillable. The outer tubes are placed over the filled inner tube and imaged, adding a tube for each image. The resulting images allow the user to determine the system’s sensitivity. Five internally stacked concentric aluminium tubes – all 700 mm in length
PET Scatter Phantom - NEMA 2001
-
Determine the imaging systems relative sensitivity to scatter radiation
-
Measure the effects of dead-time and the effects of random events generated at different levels of activity of the line source
-
The NEMA 2000 PET Scatter Phantom is designed in compliance with the recommendations of the National Electrical Manufacturers Association (NEMA-2000 Standard) to standardize the measurement of count rate performance of a scintillation camera in the presence of scatter
-
The phantom contains a fillable line source that runs parallel to the centre axis of the cylinder and offset a distance of 4.5 cm. The cylinder is made of four sections for ease of carrying and storage. There are two lock knobs and a rod to fasten the four sections together.
