Abstract: One embodiment is a method of performing thoracic tomography on a human subject including performing multiple 4-wire impedance measurements on a region of interest to obtain measured impedance data; comparing the measured impedance data to simulated impedance data obtained from a plurality of models of the region of interest; for each of the models, determining a fit of the model based on a comparison between the simulated impedance data obtained from the model and the measured impedance data; and integrating individual resistivity estimates obtained from the models based on a fit of the model such that the individual resistivity estimate from a better fitting model is weighted more heavily in a final resistivity estimate than an individual resistivity estimate from a worse fitting model.

Abstract: Aspects described herein relate to estimating mean arterial pressure (MAP) of a living being. The estimating may include obtaining pulsatile arterial blood pressure (pABP) waveform, obtaining arterial blood flow (ABF) waveform, identifying a set of segments of the pABP waveform in steady state, identifying a set of segments of the ABF waveform in steady state, and estimating the MAP based on the identified segment of the pABP waveform in steady state and the identified segment of the ABF waveform in steady state
