| Abstract: | Recently, combined PET/CT is a new imaging system which enable acquire co registered anatomic and biological function images in a single scanning session. PET/CT is valuable for improving tumor localization, planning of radiation therapy, defining biopsysite and evaluating response to therapy . CT can also provide low noise CT based attenuation correction for PET emission scan. The design and performance, clinical application,advantages and some technical limitation of a combined PET/CT scanner were summarized briefly in this paper. |
