Avotec offers three types of Silent Vision™ visual presentation systems:

SV-5400 is a composite video (400x600) resolution LCD projector. This system is a good choice for sites that will be doing primarily non-fMRI clinical work where having an easy-to-use, movie capable system is useful.

SV-6011 is an XVGA resolution (1024x768) LCD projection system. This offers the same ease of use as the SV-5400, while offering the kind of resolution demanded by research applications. The SV-6011 (and the SV-5400) system can be combined with the RE-5601™ eye monitoring system to enable eye tracking applications.

SV-7021 is a high resolution, binocular fiber optic system. These high resolution (1024x763) fiber optic glasses are all glass-plastic construction, so they are truly MR inert. This immunity to field strength, as well as their compact size, makes them the choice for demanding research applications. When integrated with the RE-4601/4621 Real Eye™ monitoring system, simultaneous binocular stimulation and eye tracking is possible.

Audio stimulation Choose from the Silent Scan™ audio systems. The SS-3000 is a clinically oriented audio system. The SS-3100 adds a equalization filtering, plus full calibration. Silent Scan headsets offer optimal noise reduction.

Trigger input Successful fMRI depends on linking the scanner time base with the stimulus time base. Avotec’s True Trigger™ trigger interface interfaces with both optical or electrical scanner trigger outputs.

Patient response is another critical aspect of fMRI. Avotec can supply your choice of patient response pads.

Eye monitoring / tracking For more sophisticated applications, consider Avotec’s Real Eye™ eye monitoring systems, which also enable video-based eye tracking applications.
