The NEMA NU 4-2008 standard proposes a standardized methodology for evaluating the performance of positron emission tomographs (PET) designed for small animal imaging.

TThe phantoms for scatter fraction, count losses and random coincidence measurements with ?PET systems are designed according to the NEMA NU4-2008 (section 4) specifications.

The phantoms are made from High Density Polyethylene (HD PE). Three different types of phantoms are available, that represent a mouse, rat or monkey size.
