Counting Rates of Vertex Camera Due to 18F Cylinder
| Energy window | Counting rate when facing source (count/min/185 MBq) | Counting rate when facing floor (count/min/185 MBq) | Counting rate when facing away from source (count/min/185 MBq) | No source (count/min) |
|---|---|---|---|---|
| 99mTc | 150,583 | 7,125 | 15,838 | 2,332 |
| 201Tl | 261,939 | 10,415 | 21,688 | 3,430 |
| 67Ga | 405,622 | 17,320 | 38,502 | 5,446 |
Source-to-detector distance was 4 m.
