Both 1.5T and 3T research scanners are equipped with stimulus delivery and monitoring systems for fMRI research. These include Epson 8100 3-LCD projectors with Buhl long-throw lenses for rear-view/rear-projection onto Mylar screens. Video signals are carried into the magnet room using a Lightwave FiberLynx optical-fiber VGA connection. Both the projector and the FiberLynx units are housed in custom RF shield boxes with filtered power receptacles. Images are viewed through mirrors mounted on the head coils.

Audio stimuli may be presented via a pneumatic Avotec system which is equipped with two different styles of head phones to accommodate variance in patient head size on both the Siemens Sonata and Trio 1.5T and 3T systems. Alternatively, there is also a pair of electrodynamic headphones available. Pulse, pulse oximetry, EKG, ET C02 and respiration can be monitored during fMRI scanning. Also, MRI-safe prescription glasses (which are compatible with all head coils) are available.

Responses are monitored using a FORP fiber optic button boxes installed at the 1.5T and 3T system. Low pass filters in the magnet room penetration panels allow custom interfacing of other stimulus and monitoring equipment using DB-9 connectors.
