High contrast microwave tomography using topology optimization techniques
Microwave tomography for medical applications leads to a difficult reconstruction problem for the dielectric properties of biological tissue due to strongly diffracting waves in combination with large dielectric contrasts. We apply the material distribution technique used for topology optimization of elastic structures in order to solve the nonlinear least-squares problem underlying the reconst...
متن کاملHigh-resolution Electrical Impedance Tomography: a Topology Optimization Approach
Electrical Impedance Tomography (EIT) finds the conductivity (in the case of the quasistatic approximation of Maxwell’s equations, for a linear and isotropic medium and a sufficiently small excitation frequency) distribution in a given model of a body which reproduces the boundary measurements of currents and potentials on electrodes attached to that body (Mello et al. [2]). The conductivity di...
متن کاملElectrical Impedance Tomography: Topology Optimization
The Electrical Impedance Tomography (EIT) is a study of body parts who use electric current. Is studied through computers resistance or conductivity of these parts, producing an image used for medical diagnosis. A body is wrapped in a blanket placed with small electrodes and receivers of electric current, potential difference. Based on data obtained from a series of measurements at the electrod...
متن کاملTopology Optimization Applied to Electrical Impedance Tomography
Abstract Electrical Impedance Tomography (EIT) is a imaging method that estimates conductivity distribution inside a body (domain). In this method, images are obtained by applying a sequence of low intensity electrical currents, through electrodes positioned around the body. Applications of EIT can be often found in geophysics sciences, non-destructive testing and medical applications. Although...
متن کاملMicrowave imaging of high-contrast objects
This thesis describes a novel approach to microwave imaging. The proposed methods are based on the spectral representation of the object. Regularization schemes for the solution of electromagnetic inverse problems are addressed. An iterative algorithm for the solution of the nonlinear least-squares problem arising in iterative image reconstruction is developed. The application of this algorithm...
