Numerous medical MRI applications suffer from patient motion and require motion control. A simple and low-cost motion tracking system is proposed which is based on the infrared light detection camera built-in in a Wii Remote (Nintendo), connected via Bluetooth to a computer for analysis. The proposed system allows for detecting patient motion with sensitivity below 40m and can become a solution for a wide range of MRI applications, in which real-time patient motion control is required.
