摘要：

The signal-to-noise ratio in magnetic particle imaging can be limited by distortion interference arising in the imaging system. In this work, we investigate the contribution of resonant transmit capacitors to system interference. Feedthrough interference spectra obtained using four capacitors with varying voltage ratings in a custom MPI interference testbed show a 20dB reduction in distortion interference with higher-rated capacitors. Finally, we discuss the applicability of the interference testbed to treat other interference mechanisms in magnetic particle imaging.
