A system and method for beamforming in soft-field tomography are provided. One soft-field tomography system includes a plurality of transducers configured for positioning proximate a surface of an object and one or more excitation drivers coupled to the plurality of transducers and configured to generate excitation signals for the plurality of transducers. The excitation signals include at least one frequency component. The soft-field tomography system further includes one or more response detectors coupled to the plurality of transducers and configured to measure a response of the object at the plurality of transducers to the excitation applied by the plurality of transducers based on the excitation signals. The soft-field tomography system also includes a soft-field reconstruction module configured to reconstruct a property distribution based on the excitation signals and the measured response using an Electrical Impedance Spectroscopy (EIS) beamformer.
