Applications of X-ray computed tomography in the geosciences

X-ray computed tomography (CT) is a non-destructive technique with wide applications in various geological disciplines. It reveals the internal structure of objects, determined by variations in density and atomic composition. Large numbers of parallel 2D sections can be obtained, which allows 3D imaging of selected features. Important applications are the study of porosity and fluid flow, appli...

Topology 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...

Topology Optimization Applied to 2d and 3d Electrical Impedance Tomography

Electrical Impedance Tomography (EIT) is an imaging technique which tries to find conductivity distribution inside a section of body. The EIT deals with an inverse problem in which given the measured voltages on electrodes it estimates the conductivity distribution by using an image reconstruction algorithm. EIT can be used in several applications and, recently, it has been applied for obtainin...

Geoinformatics: Transforming data to knowledge for geosciences

An integrative view of Earth as a system, based on multidisciplinary data, has become one of the most compelling reasons for research and education in the geosciences. It is now necessary to establish a modern infrastructure that can support the transformation of data to knowledge. Such an information infrastructure for geosciences is contained within the emerging science of geoinformatics, whi...
