PET image reconstruction with a system matrix containing point spread function derived from single photon incidence response |
Fig.#cod#x00A0;9. The reconstructed image and the middle line profile of the point array generated by MC simulation. The closest point is 140#cod#x00A0;mm off the center of the FOV, and the furthest point is 300#cod#x00A0;mm off the center of the FOV. The distance between every two points is 20#cod#x00A0;mm in both radial and tangential directions. a Reconstructed image of the point array. b Profile of the middle line points. |
