Abstract
In one embodiment, an apparatus for automatically testing and tuning a RF coil is provided. The apparatus comprises a digital frequency generator for generating a stimulus, the stimulus comprising a range of radio frequency signals having different frequencies, a radio frequency coupler configured for applying the stimulus to the RF coil so as to enable the RF coil to generate a reflected signal in response to the stimulus applied, a radio frequency detector for detecting the reflected signal and a signal processing unit for processing the reflected signal, so as to identify the tuned resonant frequency of the RF coil and further configured for calculating return loss at the RF coil based on the reflected signal.
