TL;DR: The approach in investigating the application of the PA technique in arthritis is described, and finger imaging results of a patient diagnosed with rheumatoid arthritis are presented.

TL;DR: The PD reconstructions are comparatively artifact free, providing superior absorption coefficient maps in terms of quantitative accuracy and contrast recovery, and the scaling of computation time with the dimension of the measurement set is much less steep with the Jacobian update formula in place than without it.

TL;DR: In this article, the effect of aperture width and initial specimen height on the strain distribution in the plane-strain extrusion extrusion forging of machined lead billets is observed.

TL;DR: In this article, a model based iterative image reconstruction (MoBIIR) algorithm is developed for impedance image reconstruction of Electrical Impedance Tomography (EIT), Simulated boundary data are generated for circular phantom configuration and the conductivity images are reconstructed with different regularization techniques and regularization parameters.

TL;DR: In this paper, a basis for optimising some of the parameters for simple closed-die forging is proposed, where slip-line field solutions are used to predict the flow, the load and the energy in a simple two-dimensional closed die forging operation, and the influence of the design parameters; flash-land width, excess initial workpiece area and forged cross-sectional size on complete cavity filling and efficient cavity filling are investigated.
