From: Estimation of optimal number of gates in dual gated 18F-FDG cardiac PET
Comparison of different gating schemes with (a) non-gated and dual gated PET images with (b) three respiratory and three cardiac gates, (c) five respiratory and four pulsatile gates and (d) six respiratory and five pulsatile gates in the phantom study. The hot spot is blurred in the non-gated image versus dual gated images. The hot spot in the phantom is slightly smaller in (c) and (d) whereas (d) shows slightly increased noise compared to (c).
