Abstract
This article describes the design, construction, application, and effectiveness of a simple bite bar for use with an MRI whole-head coil to reduce head-movement-related artifacts during functional brain imaging. The device is comfortable to use and allows considerable flexibility in positioning the subject's head. Eleven subjects were scanned while performing a motor-sequencing experiment with and without the bite bar. The bite bar was generally effective in reducing maximum head movement to less than 0.5 mm (translation) and 0.5° (rotation).
