MRI 每 Magnetic Resonance Imaging

Capture motion during MRI scans using Qualisys* highend MRI motion capture camera, Oqus MRI. Being completely shielded, the Oqus MRI camera is one of a kind.

MRI Motion capture
Qualisys motion capture systems can be used inside an MRI scanner room. Equipment used in conjunction with an MRI scanner should not cause any electromagnetic interference as that can result in artifacts and loss in the MRI image quality. Oqus MRI 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.

A typical measurement situation involves the capture of both brain activity and kinematics during functional MRI measurements. Synchronization to other MRI-compatible equipment, such as eye-trackers, is easily peformed.

MRI setups typically consist of three or more cameras, depending on the movement to be captured and the room dimensions. A recommended setup can be seen in the application note.
