Need A complete eye tracking system specifically designed for research studies with functional MRI. The system must work with a variety of MRI equipment, include a visual display system and optics for use outside of the magnet for training and testing. The system must also be reliable and easy to use and maintain.

Solution The ASL model R‐LRO6 is the first video based eye tracking system designed to meet these specific needs. Our long range optics module can be placed up to 16 feet from the subject,avoiding interference with the fMRI system. A small relay mirror is the only piece installed within the magnet. A second set of remote optics can be attached to the modular eye tracking control unit and used for training and testing outside the magnet. Compatibility with a variety of stimulus generation software products, including MatLab, E‐Prime and Presentation allows to create and perform gaze contingent timed events. This system meets the needs of minimal intrusion, ease of use and easy maintenance.
