Table 1 Deep learning algorithm combinations explored in this study with brief descriptions
Reconstruction number | Reconstruction and DL name | Comment |
|---|---|---|
1 | ToF-BSREM | Gold standard in the current study, widespread clinical use. |
2 | ToF-OSEM + DLE | Computationally fast. Evaluated previously [21] |
3 | OSEM + DLE + DLT | Computationally fast, Use of DLE is outside bounds of DL training data. |
4 | ToF-OSEM + DLE + DLT | Computationally fast. Use of DLT is outside bounds of DL training data. |
5 | ToF-BSREM + DLT | Use is outside bounds of DLT training data. |
