| Popis: |
The use of positron-emitting radionuclide molecular imaging is important in the diagnosis and staging of malignant disease response and monitoring of treatment. In order to cope with emerging clinical needs, the imaging performance has been greatly improved recently. These developments are usually limited by the application of positron emission tomography (PET) physics; hence the primary goal in PET scanner designing is to improve spatial resolution, sensitivity, and the ratio of true coincidence count rate relative to the noise [1]. In addition to the photon counting-related statistical effects, scattered and random coincidence processes also contribute to background noise in PET. Recent advances in new models of scintillator and electronic equipment and statistically based algorithms of PET image reconstruction have greatly improved the clinical performance of PET [2, 3]. Nowadays, the new PET imaging technology is able to complete anatomically and functionally in a few minutes, which largely reduce the waiting time in clinic while maintaining a good imaging quality. |
