Plotting:
Angle parallel to rectum
Considerations:
- Set phase A-P and compensate for aliasing.
- Saturation band inferior and superior to our FOV can help reduce artifacts.
Plotting:
Angle perpendicular to rectum
Considerations:
- Set phase H-F and compensate for aliasing.
- Saturation band inferior and superior to our FOV can help reduce artifacts.
