Steps in the multiple-acquisition frame based motion correction method. The raw list-mode data are divided into subframes (step 1). The durations of the subframes are 8.6 ± 8.7 sec for the five awake NHP studies. Each subframe is reconstructed with FBP with a Ramp filter at Nyquist frequency, without attenuation or scatter corrections (step 2). A transmission image of the same subject from an anesthetized study is resliced to the awake reference orientation (step 3). The transmission image is resliced to the orientation of each subframe (step 4). Each subframe is re-reconstructed with attenuation and scatter corrections (step 5). Finally, the subframe images are transformed to the reference orientation and grouped to 5-min frames.
