iView X™ MRI/MEG

Robust, integrated solutions, compliant and virtually artifact-free for fMRI

Widely compatible

Designed specifically for the demanding fMRI environment, the iView X™ MRI systems seamlessly integrate with most projector and goggles-based stimulus setups, and are compatible with most scanners and headcoils.

Fully mobile

The iView X™ MRI-LR is a highly mobile system that can be deployed in and removed from the imaging room within minutes. This flexible concept allows for easy integration with the scanner and projection system, providing truly remote eye movement monitoring, data recording and transmission functions. The iView X™ MRI-LR system uses elaborate Faraday shielding and fiber optics for signal transmission and infrared illumination to avoid magnetic interference with the scanner.

Comfortable operation

The iView X™ MRI-SV is designed for contact-free monitoring, recording, and transmission of high quality eye movement data. Easy to operate, the user interface provides a qualitative overview at any stage of the recording. Its low-profile design allows for comfortable operation, while the magnetically inert fiber optic goggles prevent interference.

Online monitoring

Both iView X™ MRI systems offer built-in calibration routines, online eye image and data monitoring, as well as data recording and online transmission. They are compatible with standard stimulus software. Recorded data can be analyzed using SMI's BeGaze application.

Fully equipped

The iView X™ MEG perfectly integrates with most projector and screen systems with both sitting and lying subjects. It can be set up in seconds thanks to its fast fine adjustment mechanism and eye image monitoring. In addition, the system is supplied with a customized extra-robust aluminum rig that contains all the system components in the MSR, preventing interference with the MEG system.
