Abstract: An embodiment of a wide angle personal display projector is configured for positioning in relation to a user's eyeball, and includes a curved display layer. A curved micro lens array having a curvature generally matching the display curvature is positioned relative to the display layer so that the micro lens array is between the display layer and the user's eyeball. In another embodiment, a binocular personal display system includes a frame structure for supporting left and right personal display projectors in relation to the user's left and right eyeballs.

Abstract: A head-up display and eye-tracker system, suitable for use with a patient in an MRI tube during an MRI procedure. An electronic display assembly includes an outer display tube housing for housing an electronic display device for generating images, the outer tube housing fabricated of an electrically conductive, non-ferrous material. An eye-tracker camera assembly includes an outer camera tube housing for housing an electronic camera sensor, the outer tube camera housing fabricated of an electrically conductive, non-ferrous material. An eyepiece assembly includes an outer housing. A beam splitter assembly includes a beam splitter block having a receptacle holding a beam splitter, the block formed of an electrically conductive, non-ferrous material. The beam splitter reflects light from the display onto the patient's eye, and allows light reflected from the patient's eye to pass to the camera sensor. In another embodiment as a display system, the eye-tracker camera assembly is omitted.

Abstract: An interface system for providing a signal interface between devices in a magnetic resonance imaging (MRI) magnet room and devices in the outside environment to the magnet room. An exemplary embodiment includes a signal transmission link between the MRI magnet room and the outside environment, the link including a wireless local area network. A controller system is located in the outside environment and connected to the devices in the outside environment. A transducer system is located in the MRI magnet room and connected to the devices in the MRI magnet room.

Abstract: A three-dimensional high resolution magnetic resonance imaging (MRI) video and audio system employed within the magnetic field of a bore of an MRI scanner to provide video images via a relay lens system and corresponding audible sound via a non-magnetic path to an MRI patient. The invention provides non-magnetic video sources and audio speakers for generating the images and sound, respectively, and includes a first non-magnetic shielded generating mechanism positioned within the magnetic field of the bore for providing a video image. A first optical mechanism captures and transmits the generated video image to provide a high resolution video image. A second optical mechanism magnifies and redirects the high resolution video image for viewing by the patient. A second non-magnetic shielded generating mechanism is positioned within the magnetic field of the bore for providing audible sound over the full frequency range.

Abstract: A headset is provided for an audio and video system that is compatible with the strong magnetic fields generated by Magnetic Resonance Imaging equipment. In the system, the audio portion of the signal is passed through an amplifier and appropriate RF filters and chokes, and fed into a pneumatic transducer inside the magnet room. A headset having an inner set (portion) connects the output of the pneumatic transducer to the patient's ear, while an outer set covers the patient's ear to block out gradient knocking noises.

Abstract: A display system for display of MRI, ultrasonic, patient vital sign or other imagery within a magnet room of an MRI system. An MRI compatible video display is disposed with the magnet room, and is connected to the MRI image processor to provide MRI images to medical personnel working in the magnet room. The display can be an MRI compatible LCD projection display, a wired LCD screen display, a reflective LCD screen display or a plasma display. The display within the magnet room is made MRI compatible by appropriate shielding and filtering. The display may also display patient vital sign data or imagery from an MRI compatible ultrasound apparatus.

Abstract: An audio and video system that is compatible with the strong magnetic fields generated by Magnetic Resonance Imaging equipment (wherein the MRI equipment is separated by a penetration panel into a control room and a magnet room). The system receives an incoming RF signal through a television or video cassette recorder, and then separates the RF signal into a video section signal and an audio section signal. The video section signal passes through appropriate buffering, amplifying, low pass (for the procession frequency) and RF filtering circuits, and is next conducted through the penetration panel into the magnet room where it is terminated and filtered again for spurious noise. A processor and LCD pixel driver then process the video section signal and send it to an LCD display screen. A mushroom shaped hook is mounted to the screen and a catch is mounted to a bore of a main magnet inside the magnet room so that the LCD screen can be attached to the bore.
