M imaging methods are slowly but surely trending toward the solution of an inverse problem, not only for the velocity-estimation phase but also for the migration step. The general direction is toward the conventional imaging twostep process of velocity estimation followed by migration being superseded by the single full-waveform inversion (FWI) process. However, today, advanced imaging workflow...

WE are very excited about the fact that extended versions of three outstanding papers from the Ninth Eurographics/IEEE VGTC Symposium on Visualization (EuroVis ’07) have been invited to this special section of IEEE Transactions on Visualization and Computer Graphics (TVCG). EuroVis ’07 took place in Norrköping, Sweden, from the 23rd to the 25th of May 2007 and it was in many ways a success. A r...
