In 1912, Conrad Schlumberger (1878-1932), professor at the Ecole des Mines de Paris (now MINES ParisTech), made the first electric field imaging experiment at his family house in Val Richer, in Normandy. This offered new possibilities for exploring the Earth.
One hundred years later, the workshop, held in Paris, 9 - 10 July 2012, is an excellent opportunity to gather different communities working on electrical resistivity tomography. Electrical imaging has grown to include work in the fields of geophysics, medical imaging and process tomography, and is still developing. The booklet contains extended abstracts related to oral and poster presentations, demonstrating recent progress in terms of acquisition, data processing and inversion, but also presenting challenges still to be addressed.
