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.
