Attenuation Correction for Small Animal PET Images: A Comparison of Two Methods
Figure 5
Transaxial slices of rat-phantom simulated PET images using PeneloPET. On the left side the image resulting from the simulation of uniform activity concentration with attenuation (a); on the right side the simulated image of uniform activity concentration without attenuation (b). Only in this case images were reconstructed using OSEM 3D [12].
