PET acceptance testing model

The NEMA 94 PET Phantom consists of one large outer tube, two smaller fillable tubes, one solid PTFE tube, and three stainless steel tube sources. According to standards, they can be used for various configurations to measure spatial resolution, scattering, sensitivity, counting loss and randomness, uniformity, scattering correction, counting rate correction, and attenuation correction

Purpose: A highly configurable model that can be used for multiple measurements of PET systems according to the 1994 version of NEMA standard publication NU 2 (now replaced).PET acceptance testing model（NU 2-1994）
