随着分辨率越来越高的 PET 系统的出现，与 PET 扫描仪的固有分辨率相比，少量的运动可能会导致生成的图像明显模糊。作者回顾了针对不必要的患者运动以及由于心脏和呼吸周期引起的运动的先进校正方法。运动校正方法的一个普遍主题是使用日益复杂的软件来利用现有的先进硬件。从这个意义上说，该领域对未来旨在改进运动检测、表征和补偿的新颖想法（硬件，尤其是软件）持开放态度。
With the arrival of increasingly higher-resolution PET systems, small amounts of motion can cause significant blurring in the resulting images compared with the intrinsic resolution of the PET scanner. The authors review advanced correction methods for unwanted patient motion and for motion due to cardiac and respiratory cycles. A general theme in motion correction methods is the use of increasingly sophisticated software to make use of existing advanced hardware. In this sense, the field is open to future novel ideas (hardware and especially software) aimed at improving motion detection, characterization, and compensation.
