A High-Resolution Microscopic Electrical Impedance Imaging Modality: Scanning Impedance Imaging
Electrical impedance imaging is an imaging technique which has the capability of revealing the spatial distribution of the electrical impedance inside biological tissues. Classical electrical impedance imaging including Electrical Impedance Tomography (EIT) typically has low resolution. Advances in …

Towards high-bandwidth scanning impedance imaging
… industry. By using a system of high-bandwidth impedance sensors and drive electronics, the physical constituents of ICs such as buried/surface dielectrics, buried/surface conductors and PN junctions could be detected. This thesis takes an initial step toward high-bandwidth electroquasistatic …

Development of an electrical impedance tomograph for complex impedance imaging
… project concerns the development of electrical impedance tomography towards the production of complex impedance images. The prime intention was to investigate the feasibility of developing suitable instrumentation; but not clinical applications. It was aimed to develop techniques for the …

Multi-electrode stimulation and measurement patterns versus prior information of fast 3D EIT
Electrical Impedance Tomography or as referred to as EIT, is a typical inverse problem of estimating the unknown interior material impedance properties inside a conductive medium through measurements performed at the periphery of the containing medium. Due to its inverse nature, EIT’s poor spatial …

High fidelity imaging in electrical impedance tomography
… reconstruction of images using Electrical Impedance Tomography (EIT). EIT is an imaging method, in which electrical currents are injected through electrodes into a conducting volume and the resulting potential distribution is measured at surface electrodes. From these potentials, an image …

Developing Label-free Imaging Techniques to Study Biological and Energy Conversion Processes
… technologies, plasmonic-based electrochemical imaging (PECI). It images local reactions (both faradaic and non-faradaic) without using a scanning microelectrode. Utilizing the reflectivity from surface plasmon resonance (SPR), PECI is fast and non-invasive, and its signal is proportional to …
