Electrical Impedance Tomography Reconstruction Software (EIDORS) is an open-source software tool box written mainly in MATLAB/GNU Octave designed primarily for image reconstruction from electrical impedance tomography(EIT) data, in a biomedical, industrial or geophysical setting. While the name reflects the original intention to cover image reconstruction of data from the mathematically similar near infra red diffuse optical imaging, to date there has been little development in that area. The project was launched in 1999 〔W R B Lionheart, S R Arridge, M Schweiger, M Vauhkonen and J P Kaipio, Electrical Impedance and Diffuse Optical Tomography Reconstruction Software, Proceedings of the 1st World Congress on Industrial Process Tomography, pp 474–477, Buxton, Derbyshire, 1999〕 with a Matlab code for 2D EIT reconstruction which had its origin in the PhD thesis of Marko Vauhkonen and the work of his supervisor Jari Kaipio at the University of Kuopio. While Kuopio also developed a three dimensional EIT code 〔Vauhkonen, P. J., Vauhkonen, M., Savolainen, T., & Kaipio, J. P. (1999). Three-dimensional electrical impedance tomography based on the complete electrode model. Biomedical Engineering, IEEE Transactions on, 46(9), 1150–1160.〕 this was not released as Open Source. Instead the three dimensional version of EIDORS was developed from work done at UMIST by Nick Polydorides and William Lionheart.〔 Polydorides N, Lionheart WRB, A Matlab toolkit for three-dimensional electrical impedance tomography: a contribution to the Electrical Impedance and Diffuse Optical Reconstruction Software project, Meas. Sci. Technol. 13 (December 2002) 1871–1883〕 The forward models in EIDORS use the finite element method and this requires mesh generation for sometimes irregular objects (such as human bodies), and the meshing needs to reflect the electrodes used to drive and measure current in EIT. For this purpose an interface was developed to the Netgen Mesh Generator. As the project grew there was a desire to incorporate forward modelling and reconstruction code from a variety of groups and Andy Adler and Lionheart developed a more extensible software system 〔A Adler and W R B Lionheart, Uses and abuses of EIDORS: An extensible software base for EIT, Physiol Meas 27, S25–S42, 2006.〕 The EIDORS project also includes a repository of EIT data distributed under Open Source licenses. ==External links== * (EIDORS website on Sourceforge ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EIDORS」の詳細全文を読む スポンサード リンク
