AB  - We perform on an average 30 PET/CT scans daily. A new PET/CT scanner Gemini TF 16 installed in our department in the month of September 2012 has a PET component capable of Time of Flight imaging by using lutetium-yttrium oxyorthosilicate crystals and operates in a 3-dimensional mode. Our aim was to evaluate the system before acceptance and observe the system performance for eighteen month post installation for its consistency during high volume work. Methods: Acceptance tests for a PET/CT scanner are a set of quality control tests performed after installation to verify various parameters specified by the manufacturer before utilizing the scanner for clinical use. We have performed the NEMA NU-2 2007 quality control test of this system and analyzed the results of continuous evaluation of gain calibration, timing resolution and energy resolution for a subsequent period of eighteen months. Results: Gemini TF 16 whole-body PET/CT scanner passed the entire NEMA NU-2 acceptance testing and there were not many fluctuations observed in energy and timing resolutions during this period of observation. Conclusion: Our study shows that Gemini TF 16 whole-body PET/CT scanner is able to perform excellently for the study period of eighteen months despite high volume work.
