Axial and In-Plane Motion Detected Before and After Correction for Artificial Shift Addition*
| Shift before correction (mm) | Shift after correction (mm) | ||||||
|---|---|---|---|---|---|---|---|
| Scan | x-Shift | y-Shift | z-Shift | x-Shift | y-Shift | z-Shift | |
| Simulation phantom | 6-mm axial | 0.0 | 0.0 | −5.9 | 0.0 | 0.0 | 0.0 |
| 12-mm axial | 0.0 | 0.0 | −12.0 | 0.0 | 0.0 | 0.0 | |
| Physical phantom | 8-mm oblique | −4.3 | 0.0 | −5.3 | 0.0 | −0.3 | 0.2 |
↵* For each phantom study, maximal shift in in-plane direction (x, from right to left, and y, from anterior to posterior) and axial direction (z, feet to head) is displayed.
