MRI-Live!

MRI-Live! is an integrated video display and eyetracker for fMRI. Its novel design incorporates a unique combination of technologies to provide the ultimate tool for human brain mapping:

90 degree field of view, stereoscopic display

• Two high resolution 1280x1024 pixel, high contrast, full colour digital displays combined with a novel zoom optic projection arrangement create a truly immersive environment in the scanner.
• Double the field-of-view and spatial resolution compared to other solutions.
• Independent displays for each eye support the full range of biocular, binocular and stereoscopic stimulus presentations.
• Dual DVI inputs for complete compatibility with standard graphics cards on any platform.
• No proprietary graphics hardware or software required. Use Presentation, ePrime, Psychtoolbox or any custom stimulus software system.

Fully integrated, high performance video eye tracking

• Proven CRS technology provides robust, high speed, drift free, video eye tracking synchronous with the stimulus.
• 250Hz in one eye, better than 0.1 degree resolution and 0.25 degree accuracy.
• Comprehensive Toolbox for MATLAB provided to support integration with experimental software.
• Supports automatic synchronization with the scanner triggers and third-party equipment.
• Also available in a stand-alone head-fixed configuration for use in regular laboratory studies.

MRI compatible

• Remote electronics, screened non ferromagnetic enclosure and fibre optic I/O interface to the stimulation and control computers guarantee compatibility with the scanner
• Tested for use in 1.5T and 3T systems

No susceptibility artefacts

• Passive MRI-compatible components at the head coil ensure high quality scans.
• Designed for use with 8 channel High Resolution Head Array coils in GE, Siemens and Philips whole body scanners.

Rapid deployment and setup

• A large image, close to the eyes with drop in ophthalmic lenses and a simple, quick eyetracker calibration procedure mean a better experience for the subject and a more productive time in the scanner. We realise that scan time costs money!

Above all, a scientific tool

• Originally developed by Cambridge Research Systems for Decisions in Motion: a Cognitive Systems Specific Targeted Research Project (STREP) of the 6th EU Framework Programme for Research and Technological Development.
• Installed first at the University of Regensburg in Germany and used by Prof. Dr. Mark Greenlee, with reference sites coming soon in the UK, USA and Japan
