呼吸运动会降低PET/CT的图像质量。校正移动的第一步是将数据选通到不同的运动状态。在目前的实践中，门控基于来自外部设备的信息，这些设备测量胸部位置等物理参数。各种小组已经提出了从PET数据中提取选通信号的方法。在这里，我们比较了使用主成分分析、拉普拉斯特征映射、频谱分析和灵敏度的方法。我们对不同示踪剂的临床PET列表模式数据进行了测试。我们通过减少计数和减少总持续时间来评估与VARIAN RPM系统测量的胸部位置的相关性，以及在PET数据中增加噪声时的稳定性。我们还比较了基于不同方法提取的信号选通PET数据时的SUVmax和病变位移。
Respiratory movement degrades image quality in PET/CT. The first step in correcting for movement is to gate the data into different motion states. In current practice, the gating is based on information from external devices that measure physical parameters such as the chest position. Various groups have proposed methods to extract a gating signal out of the PET data. Here we compare methods using PCA, Laplacian Eigenmaps, Spectral Analysis and sensitivity. We test the methods on clinical PET list mode data for different tracers. We evaluate correlation with the chest position as measured by the Varian RPM system, and stability under increased noise in the PET data, both by reducing counts and reducing total duration. We also compare SUVmax and lesion displacement when gating the PET data based on the signals extracted by the different methods.
