Abstract:

Preliminary tests were carried out to evaluate the performance of the magnet system in an EPR spectrometer dedicated for in vivo tooth dosimetry. To reduce spectrum distortion, a method was proposed to rectify the nonlinearity of the scanning field via correcting of the driving current. The results of preliminary tests also demonstrated the feasibility of using horizontal magnet field for in vivo EPR.

Key words: EPR, dose measurement, scanning field, nonlinear correction
