Abstract: A method includes applying a plurality of currents to a plurality of electrodes disposed on a surface surrounding an anatomical region in a subject. Further, the method includes measuring a plurality of voltages generated in response to the plurality of currents. The method also includes selecting a coarse-scale basis corresponding to a response function associated with the plurality of electrodes. Moreover, the method includes determining simultaneously an internal admittivity corresponding to the anatomical region and a contact impedance corresponding to the plurality of electrodes based on the plurality of voltages and the coarse-scale basis. The method also includes reconstructing the diagnostic image based on the internal admittivity.

Abstract: A system for managing transfer of data in a medical body area network (MBAN) is presented. The system includes one or more sensor units disposed on a patient and configured to acquire data from the patient. Moreover, the system includes one or more detachable wireless communication and battery units, where the one or more detachable wireless communication and battery units are detachably coupled to a corresponding sensor unit. In addition, the system includes a patient monitoring device in bi-directional wireless communication with the one or more detachable wireless communication and battery units and configured to receive sensor data and maintain network connectivity between the one or more wireless communication and battery units and the patient monitoring device based on an operating condition of at least one wireless communication and battery unit of the one or more wireless communication and battery units.

Abstract: The invention is focused toward enhancing a patient's mobility by providing seamless information/data transfer between medical monitoring devices such as a patient monitor, telemetry hubs, or another mobile monitoring system. The information or data, which are transferred among the medical devices include, but are not limited to, patient demographic information, wireless network, or pairing information. A set of wireless sensors (e.g. ECG, NIBP, Temp, SpO2), which are located on a patient's body, are connected wirelessly to a patient monitor, which is not a mobile device. When a clinician needs to move the patient from one location to a another location, the clinician brings the mobile monitor close to the fixed monitor to transfer the patient and wireless network information to the mobile monitor automatically. This enables the transfer of connected on-body wireless sensors from one medical device to another medical device without physically detaching them from a patient's body.

Abstract: Implementations are disclosed for monitoring a state or change in state of a physiological parameter based on measured impedance data. In certain implementations, no images are reconstructed from the impedance data. In certain implementations, a metric (e.g., distinguishability, likelihood ratios, and so forth) may be computed and compared to reference metrics or thresholds, such as for changes over time or in comparison to a standard to determine the presence or absence of a physiological state of interest or of a change in such state.
