Qualisys motion capture systems can be used inside an MRI (Magnetic Resonance Imaging) scanner room. Equipment used in conjunction with an MRI scanner may not cause any electromagnetic interference as that can result in artifacts and loss in the MRI image quality.
Qualisys MRI camera is modified to be completely shielded, in effect creating a Faraday cage. Cables are shielded too and the camera power supply is placed outside of the scanner room and fed through a filter panel. This means that no emitted noise will interfere with the scanner.
Motion capture cameras inside and outside the scanner
A typical measurement situation involves the capture of kinematics during functional MRI measurements. A small 3-camera system could be focused at measuring hand and lower body motions outside the scanner, or a larger 6-camera system could measure both hand and lower body as well as tracking head movements during the actual scan.
In addition, the motion capture system can also be synchronization to other MRI-compatible equipment, such as eye-trackers or EMG-systems.
