Direct digitization of MR data

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In magnetic resonance imaging (MRI) systems, the returned radio frequency (RF) signal is generally demodulated using analog mixers to a lower frequency where it is sampled by an analog to digital converter (ADC). The analog components used in signal demodulation induce noise and degrade the overall quality of the resulting image. To eliminate this noise we propose an efficient method to digitally process samples of the MR signal obtained at the RF level.
