Siemens Inveon PET/CT

The PET-CT is a Siemens Inveon scanner. It is equipped with all available options including a variable focus X-ray source and an extra-large 165mm detector. The PET is capable of achieving 1.6 × 1.6mm pixel spacing with its 4 rings of 16 blocks (each with 20 × 20 LSO crystal arrays) and iterative reconstruction techniques. The PET detectors provide 10-bit dynamic range at 100MHz sampling and 312ps time bins.

The maximum single-position axial PET field of view is 12.7cm, but with continuous table motion, 30cm is possible. The X-ray source operates between 35-50kVp and is specified to provide a 50-micrometer focal spot. However, this particular instrument is capable of achieving ~7 micrometers isotropic CT voxels. Using a separate physiological monitoring system, it is capable of gating acquisition to the respiratory or cardiac cycle. CT-based attenuation correction is available. The host computers have all available software options and run Acquisition Workplace 4.0. There is a standalone computer that runs Research Workplace version 4.0 that can be used to process data offline.
