Table 1.

Reconstruction time for the images shown in Fig. 10. The overall reconstruction time includes the time used for the calculation of sensitivity image, image reconstruction, reading data files, and writing images into a file. The GPU computation time includes the actual calculation time and data transferring time. Times shown in the table are all for ten iterations of list‐mode TOF‐PET image reconstruction
