A Simulation Study for the attenuation correction of Respiratory Motion with the PET/CT Gating data

摘要

Objective To investigate the effect of attenuation correction on the gating data based on the true coincidences event of detector ring with the application of PET/CT. Methods Use the software GATE that can simulate the imaging of PET/CT to do the pixel phantom simulation in order to simulate the respiratory motion of the lung in the process of PET/CT scanning. Then, do the gating process and the attenuation correction with the simulation data of GATE. Results The quality of gating images with attenuation correction is better than none attenuated images. Conclusion The quality of gating images with attenuation correction can further improve the quality of images and the accuracy of diagnosis.
