Fig.#cod#x00A0;11. The center slice of the reconstructed image of the three rod source data acquired from our PET scanner. The center of the triangle composed of the three rods is at a position 282#cod#x00A0;mm away from the center of the FOV. a The center slice of the reconstructed image. b Profile of the top rod of the center slice. c Profile of the other two rods of the center slice.
