Fast non-local means noise reduction algorithm with acceleration function for improvement of image quality in gamma camera system: A phantom study

Gamma-ray images generally suffer from a lot of noise because of low photon detection in the gamma camera system. The purpose of this study is to improve the image quality in gamma-ray images using a gamma camera system with a fast nonlocal means (FNLM) noise reduction algorithm with an acceleration...
