Abstract
Two new image reconstruction algorithms, the "Metz filter method" (MF) and the "simple EM method" (SEM), have been developed for TOFPET. The results of these new methods were evaluated systematically in computer simulation studies and compared to those produced by three established algorithms: the most-likely position method (MLP), the confidence weighting method (CW), and the estimated posterior-density weighting method (EPDW). Relative computational efficiencies and image quality descriptors such as reconstructed image resolution, noise magnitude, and quantitative accuracy have been investigated. In most cases, the MF method appears to provide a superior compromise between acceptable image quality and reasonable computation efficiency.
