SYSTEMS AND METHODS FOR SOFT-FIELD TOMOGRAPHY

摘要

One system includes a pattern generator that generates one or more excitation patterns suitable for probing a hydration level of a tissue of a subject at one or more depths from a surface of the subject into an interrogation region. Each of the excitation patterns has a spatial sensitivity at one of the one or more predetermined depths. A data analysis module receives one or more measured responses of the subject at a plurality of electrodes to excitation applied by the plurality of electrodes based on the one or more excitation patterns and determines one or more hydration changes at the one or more depths within the subject based on the measured responses. Each of the measured responses corresponds to the one of the one or more predetermined depths for which the applied excitation pattern has spatial sensitivity.

1. A soft-field tomography system, comprising:
a plurality of electrodes configured to be positioned on a surface of an interrogation region of a subject; a pattern generator configured to determine one or more excitation patterns for probing a tissue of the subject at one or more predetermined depths from the surface of the subject into the interrogation region, wherein each of the one or more excitation patterns has a spatial sensitivity at one of the one or more predetermined depths; a plurality of excitation sources coupled to the plurality of electrodes and configured to apply each of the one or more excitation patterns to the plurality of electrodes to excite the plurality of electrodes substantially simultaneously with each of the excitation patterns; and a plurality of receivers coupled to the plurality of electrodes and configured to measure one or more responses of the subject at the plurality of electrodes to the excitation applied by the plurality of electrodes, wherein each of the one or more responses corresponds to one of the one or more predetermined depths for which the applied excitation pattern has spatial sensitivity.
