Dose Calibrator Settings and Prior Data
| Reference | Dose calibrator dial setting | Implied calibration error |
|---|---|---|
| Current SIR-Spheres calibration* | 56 × 10 (model, CRC-15R) | — |
| Selwyn, 2008 (15) | — | ∼23%–31% |
| Moore, 2007 (16) | 24 × 10 (model, CRC-15R) | 29% |
| Ferreira, 2016 (17) | 32 × 10 (model, CRC-25R) | ∼20%† |
| This work | 29 × 10 (model, CRC-15R) | 23% |
* Current SIR-Spheres calibration dial setting may differ by institution and instrument; however, 56 × 10 is setting used on University of Iowa CRC-15R to match manufacturer activity specification.
↵†Estimated using CRC-15R; true discrepancy may differ slightly when using correct model (CRC-25R).
