Example images of the Deluxe Jaszczak Phantom at 10 iterations for the five reconstruction methods studied. The smallest 4.8-mm-diameter rods are resolved for each reconstruction method, as is the smallest 9.5-mm-diameter cold sphere. Small circles of radioactivity are also visible surrounding the support rods for the spheres, which appear between the wedges of hot rods. The images for each of the reconstruction methods were visually similar, with differences in noise texture being the largest effect noted. Horizontal profiles across one row of the 7.9- and 11.1-mm-diameter rods show somewhat better peak-to-valley definition of the rods for the distance-driven and rotate-and-slant projectors as compared to the other cases. A depth-compression factor of 8 was used for the rotate-and-slant projector.
