The SV-7021 fiber optic glasses are by far the most sophisticated binocular MR visual system in the world.

The all glass and plastic construction of the glasses means that the SV-7021 can be used with any magnet, at any field strength, without noise or artifacts.

Independent 3-axis mounting of each eyepiece provides mounting flexibility and ensures a stable optical base and built-in refractive correction makes it easy to accommodate all patients.

SV7021 MR Projection System

  • The SV-7021 is a binocular visual system designed for MR use. The 7021 system accepts dual, independent XVGA inputs (1024x768) or NTSC/PAL video inputs using the optional VGA converters.

    The heart of the system is a pair of fiber optic glasses. The fiber optic glasses are constructed entirely of glass and plastic, so there are no concerns about noise being introduced into the imaging process. And since the glasses are non-conductive, there are also no safety issues. The glasses also feature adjustments for refractive correction.

    The glasses are linked via a pair of fiber optic image guides to a projector, typically located at the front of the magnet. A video interface/power supply located in the control room relays the video drive signal to the projector over a fiber optic link to ensure EMI immunity. DC power is supplied over a hard-wired cable that passes through a filter on the penetration panel. The projector is mounted on a mobile cart that can be easily moved, either for maintenance or to another location. A cooling system located in the equipment room ensures long-term reliability.

    A GUI interface for color balance and an electronic shutter feature provide the tools you need for the most sophisticated visual presentation.

    The SV-7021 system can be combined with the RE-4601 or RE-4621 eye monitoring system to enable simultaneous visual presentation and eye tracking for one or two eyes.

    Three SV7021 versions are available for different head coils

    * Straight Glasses

    Straight Glasses are used for bird cage tapered coils, or for applications where there is very little space.

    * Right Angle Glasses

    Right Angle Glasses for use with capped head coils that allow access to the patient’s eyes.

    * Extended Range (XR) Glasses

    Extended Range (XR) Glasses for use with capped head coils that have very limited access to the patient's eyes.
