Overview

MRC's video cameras have been developed for the use inside the gantry or anywhere in the intervention room of an MRI scanner. They have been tested in different environments ranging from 0.23 to 9.4 T. We can equip the cameras with various lenses to optimise the field of view, magnification, and working distance for your application.


*12M camera*		*CS camera with vario lens*

Typical applications

Video observation/correlation in functional MR imaging.
Eyetracking/observation in magnetic resonance imaging systems.
MRI diagnostic in pediatrics.
Room monitoring.

The standard module is very small and fits into almost any application. If you prefer having a distance between camera and object, a vario lens is recommended. See the specification examples below for details.

The video cameras can be connected to a TV set, a VCR, or a video / frame grabber card in a PC. The camera module is based on a 1/3" b/w sensor in an MRI-compatible housing. Colour versions are also available.

Mounting options

The following pictures show different examples of camera holders for positioning our cameras in the MRI, at the headcoil, or at the wall. We can also realize customized solutions.

White/IR light sources

As an additional accessory we offer two different flexible light sources for MR compatible white or infrared illumination. One product is based on a compact LED that can be used e.g. as an illumination for eye-tracking. The other one makes use of severals LEDs which are transferred into the scanner via a fibre-bundle. Both light sources are available with infrared and with white light. Please check the manuals for more information.
