1420 Introduction: Respiratory motion introduces motion blurring and attenuation and activity mismatch artifacts in PET/CT scans. In a free-breathing PET/CT scan, the data-driven approach allows the acquisition of respiratory information and subsequent motion compensation in the PET images. The 3D CT image is usually scanned prior to the PET scan, and the CT image is also affected by respiratory motion. Different axial positions in the CT image may be in different respiratory phases due to the h...

A dedicated reconstruction algorithm, usually 4D image reconstruction, is usually required for respiratory motion compensation. The use of a dedicated reconstruction method may make it harder for implementation and can be time-consuming especially with the use of 4D reconstruction. In this study, we present a motion compensation approach that directly applied to Listmode or sinogram data. Using the proposed approach, a regular reconstruction method with minimal or no modifications can be applied...

The conventional gating approach creates a dilemma for systems with large field-of-view (FOV) such as the uExplorer system. The motion effect is localized with variable motion amplitude across the whole FOV. A conventional gating approach would increase the noise for regions without motion, or with small motion amplitude. Existing local gating approach that allows optimized locally adaptive gating numbers requires a 4D reconstruction, which is time-consuming for generating of a 3D image. Image-d...

368 Objectives: Data-driven respiratory gating (DDG) allows the detection of motion without the use of hardware devices. Tracer dynamics, especially the fast dynamics immediately following tracer injection, may affect the performance of the conventional DDG approach. Research has shown that time-varying tracer distributions can cause errors in the estimated respiratory phase, in some cases even flipping the sign of the gating signal. The goal of this study is to reduce the influence of the trace...

Data-driven respiratory gating was previous developed to extract respiratory information directly from PET listmode data. It was also shown that different regions may contribute differently to the accuracy of the motion signal, affecting the successful rate of this method. The goal of this study is to develop and evaluate methods that automatically determine the optimum regions to acquire respiratory motion signal. Maximum likely annihilation point was used to map each listmode event to 3D volum...
