Moving the Gantry

Never change the gantry position whilst a particiant is seated under the gantry!

For all "in use" positions (0, 60 & 68), traffic light should show solid GREEN LED.
In the liquefaction position (25), traffic light should show flashing GREEN LED.

After liquefaction has stopped (~9:0am), set the probe unit to the desired measurement position to be able to start a MEG measurement.

Moving probe unit from liquefaction position (25) to lower seated position (60).

  • Make sure that no one is underneath the gantry during the position change and that the gantry can move freely up to the lower seated position.

  • Press the UP button on the back side of the probe unit for a few seconds.

    • The amber Tension LED comes on to show that the probe unit is released from the latches.
  • Keep pressing the UP button until you hear the latches lock into the 60 (lower seated) position.
  • Press the DOWN button until the pobe unit stops over the latches and the green OK LED comes on.
    • If any other LED remains lit, press the UP or DOWN buttons as necessary to adjust the gantry position.

Moving probe unit from liquefaction position (25) to upper seated position (68).

  • Make sure that no one is underneath the gantry during the position change and that the gantry can move freely to the upper seated position.

  • Press the UP button on the back side of the probe unit for a few seconds.

    • The amber Tension LED comes on to show that the gantry is released from the latches.
  • Pull down the latch release bar on the back of the probe unit, and keep it pulled down.
  • Keep pressing the UP button past the lower seated position (60) until the gantry reaches the upper seated position (68) and the movement stops.
  • Press the DOWN button until the gantry stops over the latches and the green OK LED comes on.
    • If any other LED remains lit, press the UP or DOWN buttons as necessary to adjust the gantry position.

Moving probe unit from liquefaction (25) position to supine position (0).

  • Make sure that no one is underneath the gantry during the position change and that the gantry can move freely to the supine position.

  • Press the UP button on the back side of the probe unit for a few seconds.

    • The amber Tension LED comes on to show that the gantry is released from the latches.
  • Pull down the latch release bar on the back of the probe unit and keep it pulled down.
  • Press the DOWN button until the gantry passes the liquefaction position (25) and stops over the latches at the supine position (0) and the green OK LED comes on.
    • After the gantry has rotated downwards and passed the 25° position, you can release your hand from the latch bar.
    • If any other LED remains lit, press the UP or DOWN buttons as necessary to adjust the gantry position.

When MEG measurements have finished for the day, move the probe unit to the liquefaction position (25) to allow liquefaction to run efficiently.

Moving probe unit from supine position (0) to liquefaction position (25).

  • Remove the bed from the probe unit.

  • Make sure that no one is underneath the gantry during the position change and that the gantry can move freely to the liquefaction position.

  • Press the UP button on the back side of the probe unit until you hear the latches lock into the liquefaction (25) position.

  • Press the DOWN button until the probe unit stops over the latches and the green OK LED starts flashing.
    • If any other LED remains lit, press the UP or DOWN buttons as necessary to adjust the gantry position.

Moving probe unit from upper/lower seated position (68/60) to liquefaction position (25).

  • Remove the chair from the probe unit.

  • Make sure that no one is underneath the gantry during the position change and that the gantry can move freely to the liquefaction position.

  • Press the UP button on the back side of the probe unit for a few seconds.

    • The amber Tension LED comes on to show that the gantry is released from the latches.
  • Pull down the latch release bar on the back of the probe unit.
  • Keep the latch release bar down and press the DOWN button.
  • Keep pressing the DOWN button. When the probe unit has passed the 60° position latches, release the latch release bar without releasing the DOWN button.
