Objective: To present the first 3D CGO-based absolute EIT reconstructions from experimental tank data. Approach: CGO-based methods for absolute EIT imaging are compared to traditional TV regularized non-linear least squares reconstruction methods. Additional robustness testing is performed by considering incorrect modeling of domain shape. Main Results: The CGO-based methods are fast, and show strong robustness to incorrect domain modelling comparable to classic difference EIT imaging and fewer boundary artefacts than the TV regularized non-linear least squares reference reconstructions. Significance: This work is the first to demonstrate fully 3D CGO-based absolute EIT reconstruction on experimental data and also compares to TV-regularized absolute reconstruction. The speed (1-5 seconds) and quality of the reconstructions is encouraging for future work in absolute EIT.

Background: An easy-to-operate ECG recorder should be useful for newborn screening for heart conditions, by health care workers --or parents. We developed a one-piece electrode strip and a compact, 12-lead ECG recorder for newborns. Method:We enrolled 2,582 newborns in a trial to assess abilities of parents to record a 12-lead ECG on their infants (2-4 weeks-old). Newborns were randomized to recordings by parents (1,290) or our staff (1,292 controls). Educational backgrounds of parents varied, including 64% with no more than a high school diploma.Results: For newborns randomized to parent recorded ECGs, 94% of parents completed a 10minute recording. However, 42.6% asked for verbal help, and 12.7% needed physical help.ECG quality was the same for recordings by parents versus staff. Conclusions:By use of a one-piece electrode strip and a compact recorder, 87% of parents recorded diagnostic quality ECGs on their newborn infants, with minimal assistance.
