Abstract
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 located in a patient bore of a medical imaging system. The mechanism includes a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. A pump inflates the pneumatic device to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. A vent valve vents air from the pneumatic device to return the optical device to the first position.
