Abstract：The PET-CT (Positron Emission Tomography - Computed Tomography) market in China has long been monopolized by imported products. However, current medical equipment designed in China is far from meeting the clinical requirements. ARRAYS Medical Imaging Corporation has a thorough knowledge of the core techniques of PET-CT and production of the integrated system. Its new product, RAY-SCAN 64 PET/CT, demonstrated excellence in the performance test and was successfully validated by China Food and Drug Administration (CFDA) in February2014. According to the test result, the spatial resolution of CT is 0.35 mm and the best resolution of PET achieves 3.4 mm, which indicates RAY-SCAN 64 PET/CT is comparable with the leading products in the market. In its clinical test, the image quality of brain, chest, abdomen, pelvic and lesion region scans were respectively analyzed by the General Hospital of Chinese People's Liberation Army and Beijing Cancer Hospital. Moreover, in comparison with two products from foreign companies under the same testing conditions, RAY-SCAN 64 PET/CT demonstrated no significant differences in its clinical performance.
