Figure 1

Simulated images in the study with Utah phantom (with a hot and a cold cylinder). On left side of the figure, in the first row, are the acquired PET images of the phantom: first transversal view and then coronal view. The next row shows the simulated images with a translational motion of 5mm (in 3axis) and 5 degree of rotation. The last row corresponds to the corrected images using PRESTO. On the right side of the figure are the graphs representing the absolute errors of ITK values. The graphs represent translation and rotation along the x-axis. The other two axes are not represented here but they have the same behavior as the x-axis.
