Abstract: Lorentz force electrical impedance tomography (LFEIT) combines ultrasound stimulation and electromagnetic field detection with the goal of creating a high contrast and high resolution hybrid imaging modality.In this study,pulse compression working together with a linearly frequency modulated ultrasound pulse was investigated in LFEIT.Experiments were done on agar phantoms having the same level of electrical conductivity as soft biological tissues.The results showed that:(i) LFEIT using pulse compression could detect the location of the electrical conductivity variations precisely;(ii) LFEIT using pulse compression could get the same performance of detecting electrical conductivity variations as the traditional LFEIT using high voltage narrow pulse but reduce the peak stimulating power to the transducer by 25.5 dB;(iii) axial resolution of 1 mm could be obtained using modulation frequency bandwidth 2 MHz.
