Objective(s): We evaluated edge artifacts in relation to phantom diameter and reconstruction parameters in point spread function (PSF)-based positron emission tomography (PET) image reconstruction. Methods: PET data were acquired from an original cone-shaped phantom filled with 18F solution (21. 9 kBq/mL) for 10 min using a Biograph mCT scanner. https://fitnessgravesyardes.shop/product-category/folding-latch-lock/
