| Popis: | Respiratory gating reduces motion blurring in cardiac SPECT. Here we aim to evaluate the performance of three respiratory gating strategies using a population of digital phantoms with known truth and clinical data.We analytically simulated 60 projections for 10 XCAT phantoms withFor simulations, AG and CG methods showed significantly lower RD and RSD compared to TG, while noise variation was more non-uniform through different gates for AG. In the clinical study, AG and CG had smaller FWHM than TG.AG and CG methods show better performance for motion reduction and are recommended for clinical respiratory gating SPECT implementation. |
