From: Aortic valve imaging using 18F-sodium fluoride: impact of triple motion correction
Overall scheme for simultaneous cardiorespiratory and gross patient motion detection and correction of 18F-NaF aortic valve PET scans. A fixed number of respiratory and electrocardiogram (ECG) gates (4 each) were used. The number of patient repositioning gates depended on the number of repositioning events the patient had during the acquisition. A 3D mesh of gated reconstructions were obtained, which were registered to generate the 3 × MC image set. 3 × MC = triple motion-corrected
