摘要：
Magnetic induction tomography (MIT) aims at the contact-less imaging of the electrical conductivity and related pathophysiological processes. Systems operating at frequencies below 1 MHz are desirable but suffer from poor SNR which can be dramatically impaired by mechanical vibrations. We present an algorithm which suppresses vibration noise in the imaginary part of the data and improves the SNR up to 35 dB.
