Positron Range Corrections and Denoising Techniques for Gallium-68 PET Imaging: A Literature Review
Gallium-68 (68Ga) is characterized by relatively high positron energy compared to Fluorine-18 (18F), causing substantial image quality degradation.Furthermore, the presence of statistical noise can further degrade image quality.The aim of this literature review is to identify the recently developed positron range correction techniques for 68Ga, as
