    On April 24–26 2014, the 15th International Conference on Biomedical Applications of Electrical Impedance Tomography (EIT 2014) takes place at the Glen House Resort in Gananoque, Canada. Exciting developments are taking place in EIT: developments in hardware, software, and reconstruction algorithms, and new clinical applications and better understanding of the current ones. This paper introduces this fascinating conference.

    EIT shows potential for monitoring fast changing conductivity profiles, such as heart and lung physiology and chemical processes. In such cases, the measurements which constitute an EIT frame are not taken simultaneously. Several approaches have been proposed to interpret such data, but have not been systematically compared. We formulate and compare temporal EIT solvers on simulation data.

    Steam-assisted gravity drainage (SAGD) is a technique that has been developed to efficiently extract bitumen from deep reservoirs. We propose using electrical impedance tomography (EIT) for real-time monitoring of SAGD wells to maintain optimal operating conditions. Several electrode configurations along the pipelines and measurement strategies are presented and compared.

    BioImpedance Spectroscopy (BIS) have been investigated in many research areas as a method to detect changes in living tissues. However, BIS measurements are known to be hardly reproducible in clinical applications. This article proposes segmental spectral decomposition as a method of extracting reproducible parameters from raw BIS. The efficiency of this method is then compared to conventional Cole-Cole parameter extraction in a classification task.

    Electrical impedance tomography (EIT) creates tomographic images from surface electrical stimulation and measurement. Many research and commercial devices have been made, with correspondingly many data formats, which negatively impacts the ability to share data. To address this issue, we have developed the OEIT data format, an XMLbased flexible container format for EIT data. We describe its features and structure.
