With Oqus MRI, capturing both brain activity and kinematics during functional MRI measurements have never been easier. Designed for use inside an MRI room, the Oqus MRI is truly a unique motion capture camera.
Although most modern MRI scanners have a very rapid drop off in magnetic field strength close to the scanner itself, materials used inside an MRI room should be non-metallic to the extent possible. The Oqus MRI compatible camera is purpose-built and differs from a regular motion capture camera through shielding and the selection of materials. The housing is made of die-casted aluminium, steel fasteners are replaced by brass screws and the calibration L-frame and wand is made from glass fiber. The camera is completely shielded to keep electro magnetic emissions to a minimum and enabling cameras to operate just a meter away from the scanner without causing artifacts in the MRI image.
A minimal camera system of only three cameras can be sufficient to track hand and finger movements outside the scanner bore. A larger six camera system can provide the possibility to look into the bore and even track the movements of the head during a scan.
