چکیده
Abstract Three-dimensional (3D) visualization has provoked interest in electrical capacitance tomography (ECT) due to recent progress the development of measurement circuits and data-acquisition systems. This paper proposes image reconstruction using spatio-temporal sampling Z -axis for 3D ECT improve spatial resolution. In a typical application ECT, multi-phase flow imaging is performed through two-dimensional (2D) data acquisition 2D frames over time. presented method, volume (VOI) reconstructed from several time samples obtained sensor. The procedure Jacobian matrix extension described. experiments were carried out EVT4 system 32-electrode results VOI single are compared. A phantom assess resolution modulation transfer function proposed.

Temporal image reconstruction in electrical impedance tomography.
Electrical impedance tomography (EIT) calculates images of the body from body impedance measurements. While the spatial resolution of these images is relatively low, the temporal resolution of EIT data can be high. Most EIT reconstruction algorithms solve each data frame independently, although Kalman filter algorithms track the image changes across frames. This paper proposes a new approach wh...

Electrical Capacitance Tomography is an ill-posed inverse problem that aims at recovering the spatial permittivity distribution of an inhomogeneous medium from capacitance measurements at the boundary. We consider the problem of fast robust estimation of inclusion shape and position in binary mixtures. The boundary of the inclusion is represented implicitly using a radial basis function represe...

Electrical capacitance tomography (ECT) is a non-invasive imaging technique that aims at visualization the permittivity distribution of dielectric materials based on the measured capacitances. In this paper, the 3D finite element models of a direct 3D ECT sensor with or without dielectric spheres inside the sensor are set up by using finite element modeling. The sensitivity analysis of the sens...
