Components Required for Acquiring CLI, RLI, and Block-RLI
| Component | CLI | RLI | Block-RLI |
| Charge-coupled device camera | Yes | Yes | Yes |
| Scintillator | No | Yes | Yes |
| Steel | No | No | Yes |
| Object | Yes | Yes | Yes |
| Exposure time (s) | |||
| In vitro | 30–180 | 10–60 | 10–60 |
| In vivo | 300 | 10 | 10 |
Scintillator and steel plates were placed directly above object. β-RLIs were computed by subtracting block-RLI from RLI.
