讨论了一种确定正电子发射断层扫描 (PET) 中旋转棒传输研究的最佳棒窗口宽度的技术。杆窗可降低旋转杆传动研究中的噪音。与杆相交的响应线(LOR)主要产生真正的重合事件。远离杆的 LOR 会产生随机和散射事件。由于旋转杆的角位置是实时已知的,因此产生主要噪声的 LOR 被关闭。<<ETX>>
A technique that determines optimal rod window width for rotating rod transmission studies in positron emission tomography (PET) is discussed. Rod windowing reduces noise in rotating rod transmission studies. Lines-of-response (LOR) which intersect the rods generate primarily true coincidence events. LORs which pass far from the rods generate random and scatter events. Since the angular position of the rotating rods is known in real-time, LORs, which produce mostly noise are gated off.<<ETX>>
