MoTrak - Head Motion Tracking System

Designed for use in an MRI simulator, MoTrak software uses Ascension Technology’s Flock of Birds. The sensor attaches to the subject’s head and determines the position of the head in space relative to the transmitter. The sensor records angular rotations as well as positional displacements from an initially calibrated position. This information is displayed and logged by the program in real-time, allowing observation of head motion in an MRI simulator.

In the simulator, the participant can simultaneously be habituated to the MRI environment, while being trained to remain still via feedback from the MoTrak system.
