摘要: Objectives The partial volume effect (PVE) has a great impact in quantitative PET/CT imaging. Correction methods have been recently proposed by many authors to make the image quantification more accurate. This work presents methodology for determining recovery coefficients (RCs) PVE correction images. It was taken into account radioactivity outside field of view (FOV), which is expected patient acquisition.
