Final results of model observer study (A) and human observer study (B), providing comparison and ranking of 4 algorithms studied. Model observer results plot area under LROC curve versus number of iterations, where optimal filter for each iteration and algorithm was applied (as determined from results shown in Fig. 4). Note that reconstructions with TOF provided markedly higher performance at earliest iterations, showing that the most important image features for lesion detection are recovered more quickly when using TOF. Human observer LROC curves demonstrate distinctions in performance for 4 algorithms, and confirm model observer results. Quantitative results for these curves are provided in Table 2.
