همانند اغلب سیستمهای تصویربرداری، کارآیی و کیفیت تصاویر در pet نیز با نویز آماری محدود شده است. با محاسبه دقیق زمان ورود دو فوتون با انرژیkev 511 در حلقه آشکارسازهای دور بیمار، مکان نابودی قابل محدود شدن در یک بازه است. این تکنیک که به طور قابل ملاحظه ای می تواند نویز آماری در مقادیر بازسازی شده را کاهش دهد، tof pet نامیده می شود. تعدادی دوربین pet با توانایی اندازه گیری tof در دهه 80 میلادی سا...

Introduction: Since 1954, after the first surgical repair of tetralogy of Fallot (TOF), several innovations have occurred in cardiac surgery, especially in children. One stage complete repair of TOF is currently possible even in infancy; however, complications such as hypoxemia, arrhythmia, cardiac dysfunction, sudden death, and valvular disorders may happen. In this study, we evaluated the res...

Objective(s): The present study was conducted to examine whether the standardized uptake value (SUV) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (PET) images, obtained via two methods based on time-of-flight (TOF) reconstruction and point spread function (PSF). Methods: A cylinder phantom with the sphere (30mm diameter), located in...

Cyperus rotundus (CR) is a traditional medicinal herb, and recent studies demonstrated its pharmacological effects to cure neurological disorders. In our earlier reports, we also found that CR exerts anxiolytic effects and improves memory impairment in hypoxia-induced rats. In vitro CR also effectively ameliorates oxidative stress-induced SH-SY5Y neuronal cell damage. In the present study, we e...
