TL;DR: Noise performance, spatial resolution and convergence rate applied to time difference EIT were studied, and the primal dual interior point method (PDIPM), the linearised alternating direction method of multipliers (LADMM) and the spilt Bregman (SB) method had the fastest calculation speed but worst resolution due to the exclusion of the second-derivative.

TL;DR: A method for joint calibration of several types of linear and nonlinear mismatch errors in two-channel TI-ADCs using a normalized least-mean square (N-LMS) algorithm as well as a certain low degree of oversampling for the overall converter to estimate and compensate for the mixed mismatch errors.

TL;DR: This work analyzes the influence of nonlinearity mismatches by using a polynomial model and uses the signal-to-noise and distortion ratio (SNDR) as a cost measure and derives a compact formula describing the dependency on nonlinearities mismatches.

TL;DR: The proposed MFEIT method with TV regularization shows higher spatial resolution, particularly at the edges of the perturbation, and stronger noise robustness, and its image noise and shape error are 20% to 30% lower than the traditional fraction method.

TL;DR: The proposed bioimpedance emulation method can emulate the impedance frequency characteristics of various biological samples from user configurations and offers advantages in flexibility, repeatability, and cost-efficient compared to more traditional approaches, simplifying the validation process of electrical impedance tomography systems.
