Study on performance evaluation system for transcranial magnetic stimulation devices

Transcranial magnetic stimulation devices have been widely used for clinic and research purposes and their performance such as stimulation strength, depth and focality are of great concern from various studies. However, there is no specific evaluation index nowadays. TMS devices could only be appraised qualitatively with accurate parameters, thus, a preliminary evaluation work for TMS devices is proposed in this paper. Practical indexes are proposed in order to give a clear image of the TMS device performance. This work may provide a design guideline for TMS device, performance evaluation and comparison as well.
