Table 2.
Patient size | Preset Family (Scan FOV, focal spot, coverage) | Rot time (s) | Pitch | Min CTDIvol (mGy) | Max CTDIvol (mGy) |
---|---|---|---|---|---|
Small | Large Body, Large, 80 mm | 0.5 | 1.531 | 3.1 | 7.9 |
Medium | Large Body, Large, 80 mm | 1 | 1.375 | 6.3 | 16.8 |
Large | Large Body, Large, 80 mm | 0.8 | 0.508 | 14.0 | 36.8 |
Extra large | Large Body, XLarge, 80 mm | 1 | 0.508 | 49.7 | 53.7 |
This profile is designed for abdomen and pelvis protocols where patient motion is not an issue, so long rotation times and low pitches are acceptable.
