Abstract: A computer-implemented method that includes processing a EIT data set of a subject to determine one or more conductivity characteristics associated with a tissue or organ of the subject, and, determining, based on at least the one or more determined conductivity characteristics, a health state or condition of the tissue or organ of the subject.

Abstract: A portable device of a medical screening system comprises a current generation module, a signal distribution and readout module, a data acquisition module, and a control and output module. The current generation module generates electric current signals for providing to a subject. The signal distribution and readout module provides the generated electric current signals to the subject and receives responsive electric signals from the subject, both via a wearable device with electrodes. The data acquisition module processes the responsive electric potential signals received from the subject to determine potential difference signals. The control and output module processes the potential difference signals and transmit the processed signals to a server for determining electrical impedance tomography data and medical screening result.
