Date posted: 29/03/2006 Scientists can peer inside high-pressure reactors and oil pipelines, to assess damage or improve efficiency, thanks to a new and more accurate imaging technique. The improved form of Electrical Capacitance Tomography (ECT) has been developed by Liang-Shih Fan at Ohio State University, US. It generates 3D images by measuring the capacitance of solids, liquids and gases, using a magnetic field. An ECT device onstructs a 3D image from multiple slices, each one measuring the capacitance of substances. The resulting picture shows a "slice" of the tube or generator at any moment. These snap shots can be taken many hundred times a second, and putting them in sequence generates an animation of what is happening inside. Rings of electrodes spaced along a tube can gather enough information to allow a computer to construct a full 3D video.
