The Application of GATE and NCAT to Respiratory Motion Simulation in Allegro PET

Respiratory motion artifacts can be a significant factor that limits the PET image quality. To compensate respiratory motion, simulation using software packages may provide a valuable tool for the assessment of respiratory motion detection and correction. In this study, we investigate respiratory motion by simulation using GATE (GEANT4 Application Tomographic Emission) [Jan, et al., 2005] and NCAT (NURBs(Non Uniform Rational B-Splines) Cardiac Torso) [Segars, et al., 2001] software packages.
