Abstract: SHR22000 is a whole-body PET scanner developed by Hamamatsu Photonics K.K. The scanner has a 600mm patient aperture and a 225mm axial FOV, which can cover the whole human head and large portion of the body so that a common whole-body scan can be accomplished within 5 bed position with a 3.2mm average transverse resolution at 10mm from the axis of FOV. The paper gives a system performance evaluation of this scanner using GB/T 18988.1-2003/IEC 61675-1:1998 standard, which includes the spatial resolution, tomographic sensitivity, count rate characteristic, scatter fraction and recovery coefficient. At last a human body scanning result is given as an imaging example.
