Conductivity reconstructions using real data from a new planar electrical impedance tomography device
Abstract In this paper, we present results of reconstructions using real data from a new planar electrical impedance tomography device developed at the Institut fur Physik, Johannes Gutenberg Universitat, Mainz, Germany. The prototype consists of a planar sensing head of circular geometry, and it was designed mainly for breast cancer detection. There are 12 large outer electrodes arranged on a ring of radius cm where the external currents are injected, and a set of 54 point-like high-impedance inner electrodes where the induced voltages are measured. Two direct (i.e. non-iterative) reconstruction algorithms are considered: one is based on a discrete resistor model, and the other one is an …
High voltage stabilisation for an on-line isotope separator
Abstract Stabilisation for a high voltage generator up to 60 kV has been developed. The voltage is stable within ±0.1 V. This allows the very accurate acceleration of charged particles.
