Abstract
A miniature, low-power, optical sensing device that operates in the harsh electromagnetic environment of a magnetic resonance imaging system is provided. The device includes a means of transferring imaging data obtained with the optical sensor out of this harsh electromagnetic environment without requiring a galvanic connection. It is practical to power the device using a small battery that is compatible with the harsh environment. In other embodiments, the device is powered using 'power over fiber' or by taking power by 'power harvesting' directly from the harsh electromagnetic environment. One embodiment is to directly integrate the device into a magnetic resonance imaging (MRI) head coil, using a wired connection to the head coil to provide electrical power. Here the wired connection does not penetrate the Faraday cage of the MRI system or cross into the bore of the MRI system from outside the bore.
