Head and body movements introduce artifacts in structural, diffusion, and functional MRI. With the advent of imaging at ultra-high field, head and body movements limit our capacity to obtain high-resolution, high-quality data. We have developed a small wearable device for acquiring data on head and body movements and transmitting it wirelessly to a computer for real-time analysis while a subject is trained in a mock MRI scanner. This device works in parallel to an in-bore camera used for movement detection, to support subject screening and training to remain still in preparation for MRI.
