Checking the laser light

Adjust the cradle position and check the alignment of the laser light.

About this task

The laser lights are pre-adjusted at the factory and do not usually require realignment after the initial installation alignment procedures are completed.

Procedure

  1. Adjust the cradle position to examine the laser light alignment.
    1. Move the cradle in so that the bridge edge aligns with the cradle joint end cover.
    2. Press Landmark.
    3. Move the cradle out 8 mm.
      Note: S and I shown on the display changes according to the patient orientation (head first or feet first).
      Note: The right side panel is a mirror image of the left side panel. The Out button is located at the far side of the panel away from the magnet bore.

  2. Examine the laser line for correct alignment.
    Figure 2. Correct alignment
    • The axial light must align with the cradle joint. The cradle joint end cover must be located 8 mm away from bridge end on each side.
    • The sagittal light must align with the middle line of the cradle.
    • If the laser lights are aligned correctly, make a mark with a pen in the locations of the axial light and the saggital light, as shown in the figure. These marks will be the reference for future alignment light checks. After you make these marks, this procedure is complete.
    • If the laser lights are not aligned correctly, align them. See Aligning the laser light.
