1. A displacement mechanism for placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is moved into a patient bore of a medical imaging system by a patient bed wherein the patient's head is oriented in a horizontal position in the patient bore, comprising:
a pneumatic device that extends in a downward direction toward the patient when the pneumatic device is inflated;
a resilient element attached between a top surface of the patient bore and the optical device wherein the resilient element extends downward from the top surface and through the pneumatic device wherein the optical device is suspended from the top surface and spaced apart from the patient's eyes in a first position and wherein the patient bore forms a confined space around the patient's head;
further including a guide element attached to the top surface of the bore to enable movement of the resilient element and optical device in a longitudinal direction corresponding to a longitudinal axis of the system;
a pump that inflates the pneumatic device in a downward direction to move the optical device downward to a second position wherein the optical device is placed on the patient's eyes when the patient is moved into the patient bore and the patient's head is oriented in the horizontal position and wherein inflating the pneumatic device extends the resilient element and biases the resilient element to return to the first position and wherein the pneumatic device, resilient element and optical device are preinstalled in the patient bore before the patient is moved into the patient bore; and
a vent valve that vents the pneumatic device to deflate the pneumatic device wherein upon deflation of the pneumatic device the bias of the resilient element causes upward movement of the optical device to return the optical device to the first position.
