Notes. Computing times are shown for a 128 px × 128 px image. For radionets, the runtimes are split into pure deep-learning reconstruction times (DL reco) and reconstruction times including data operations (DL reco + I/O). The programs are run for 100 times on one image. The presented values are the mean runtimes with standard deviations. Pure deep-learning reconstruction times (DL reco) just include the time needed for applying the deep-learning model. Evaluation times including data loading, model loading, and data saving (DL reco + I/O) are significantly longer as these data operation tasks are not yet optimized.
