EPR can be used to estimate exposed radiation dose by measuring the amount of free radicals in the crystalline structure of the tooth enamel. In this work, we consider a potentially detachable, flexible resonant loop as a sensing probe. The flexible loop is conformal for a better fit to patient dependent variable incisor teeth geometries. Furthermore, this single use resonant loop eliminates the need for cleaning between subjects and increases the throughput by allowing the placement of the resonant loop prior to positioning the subject in the magnet. The loops can be fabricated using high volume, lower cost manufacturing methods.
