ABSTRACT:
A viewing system for entertaining patients confined within a magnetic imaging device for prolonged periods of time. A remote source of moving video images feeds its output to a liquid crystal display projector that is positioned in close physical proximity to and within the magnetic field of the imaging device. The projector projects the moving video images onto a wooden screen that is also positioned in close physical proximity to and within the magnetic field of the imaging device. The screen is in substantial axial alignment with the longitudinal axis of the imaging device. The patient within the tube may wear spectacles that bend the light emanating from the projection screen into the patient's eyes so that the moving image on the screen can be viewed by a patient lying on his or her back and gazing upwardly at right angles to the projection screen. Alternatively, a non-metallic mirror member may be positioned within the tube so that the patient need not wear the special spectacles. Audio signals are delivered to the patient through air hoses connected to a headphone. The air hoses are fed audio signals by associated conical shaped members that are positioned within associated tubes, each of which has a first end that is closed by conventional speakers that are driven by selected sources of audio signals.
