The answer
Radial Scan uses a fixed scan length of 6.0mm and reverses the Line-Scan start point and rotation direction between eyes. The right eye rotates counterclockwise in the horizontal direction; the left eye rotates clockwise.

The eye-dependent direction is part of the scan definition, not an operator error. The manual states that the start point for Line Scan and the rotating direction are reversed for the right and left eyes.
- Scan length:
6.0mm, fixed. - Right eye: counterclockwise rotation in the horizontal direction.
- Left eye: clockwise rotation in the horizontal direction.
When checking a radial acquisition, confirm that the correct eye is selected before interpreting the orientation of the numbered radial lines. A difference in apparent scan direction between right-eye and left-eye data is therefore expected under the documented scan definition.
