APPLICATION OF NEW ALGORITHMS OF ELECTRICAL IMPEDANCE TOMOGRAPHY IN BIOMEDICINE
Original language description
This paper describes an usage of new techniques to solve electrical impedance tomography (EIT) inverse problem in the biomedical engineering. Usually, a set of voltage measurements is acquired from the boundaries of an investigated volume, whilst this issubjected to a sequence of low-frequency current patterns. In principle, measuring both the amplitude and the phase angle of the voltage can result in images of the electric conductivity and permittivity in the interior of a body. It is well known thatwhile the forward problem is well-posed, the inverse problem is nonlinear and highly ill-posed. The recently described methods are based on deterministic or stochastic approach to solve mainly 2D problems. The aim of this paper is to introduce new techniques of reconstruction of EIT images for their using in a biomedicine. New techniques, which make use of combination of well known methods for reconstruction EIT images (Total Variation Method and Tikhonov Regularization Method) and metho
